gh-78889: Stop IDLE Shell freezes from sys.stdout.shell.xyz (GH-121876)
Problem occurred when attribute xyz could not be pickled.
Since this is not trivial to selectively fix, block all
attributes (other than 'width'). IDLE does not access them
and they are private implementation details.

When using the ** operator or pow() with Fraction as the base
and an exponent that is not rational, a float, or a complex, the

When builtin static types are initialized for a subinterpreter, various "tp" slots have already been inherited (for the main interpreter). This was interfering with the logic in add_operators() (in Objects/typeobject.c), causing a wrapper to get created when it shouldn't. This change fixes that by preserving the original data from the static type struct and checking that.

On heavily loaded machines, the subprocess may finish its sleep before
the parent process manages to synchronize with it via a failed lock.
This leads to errors like:
Exception: failed to sync child in 300.3 sec
Use pipes instead to mutually synchronize between parent and child.

gh-117983: Defer import of threading for lazy module loading (GH-120233)
As noted in gh-117983, the import importlib.util can be triggered at
interpreter startup under some circumstances, so adding threading makes
it a potentially obligatory load.
Lazy loading is not used in the stdlib, so this removes an unnecessary
load for the majority of users and slightly increases the cost of the
first lazily loaded module.
An obligatory threading load breaks gevent, which monkeypatches the
stdlib. Although unsupported, there doesn't seem to be an offsetting
benefit to breaking their use case.
For reference, here are benchmarks for the current main branch:
```
❯ hyperfine -w 8 './python -c "import importlib.util"'
Benchmark 1: ./python -c "import importlib.util"
Time (mean ± σ): 9.7 ms ± 0.7 ms [User: 7.7 ms, System: 1.8 ms]
Range (min … max): 8.4 ms … 13.1 ms 313 runs
```
And with this patch:
```
❯ hyperfine -w 8 './python -c "import importlib.util"'
Benchmark 1: ./python -c "import importlib.util"
Time (mean ± σ): 8.4 ms ± 0.7 ms [User: 6.8 ms, System: 1.4 ms]
Range (min … max): 7.2 ms … 11.7 ms 352 runs
```
Compare to:
```
❯ hyperfine -w 8 './python -c pass'
Benchmark 1: ./python -c pass
Time (mean ± σ): 7.6 ms ± 0.6 ms [User: 5.9 ms, System: 1.6 ms]
Range (min … max): 6.7 ms … 11.3 ms 390 runs
```
This roughly halves the import time of importlib.util.

* parse_intermixed_args() now raises ArgumentError instead of calling
error() if exit_on_error is false.
* Internal code now always raises ArgumentError instead of calling
error(). It is then caught at the higher level and error() is called if
exit_on_error is true.

The check for whether the log file is a real file is expensive on NFS
filesystems. This commit reorders the rollover condition checking to
not do the file type check if the expected file size is less than the
rotation threshold.

The tests are now passed with the current version of Tcl/Tk under
development (8.7b1+ and 9.0b3+).
The following changes were also made to make the tests more flexible:
* Helper methods like checkParam() now interpret the expected error message
as a regular expression instead of a literal.
* Add support of new arguments in checkEnumParam():
- allow_empty=True skips testing with empty string;
- fullname= specifies the name for error message if it differs from the
option name;
- sort=True sorts values for error message.
* Add support of the allow_empty argument in checkReliefParam():
allow_empty=True adds an empty string to the list of accepted values.
* Attributes _clip_highlightthickness, _clip_pad and _clip_borderwidth
specify how negative values of options -highlightthickness, -padx, -pady
and -borderwidth are handled.
* Use global variables for some common error messages.
