A number of special cases exist:
* Tcl/Tk libraries can be built so they are not thread-aware. In this case,
:mod:`tkinter` calls the library from the originating Python thread, even
if this is different than the thread that created the Tcl interpreter. A global
lock ensures only one call occurs at a time.

lock ensures only one call occurs at a time.
* While :mod:`tkinter` allows you to create more than one instance of a :class:`Tk`
object (with its own interpreter), all interpreters that are part of the same
thread share a common event queue, which gets ugly fast. In practice, don't create
more than one instance of :class:`Tk` at a time. Otherwise, it's best to create
them in separate threads and ensure you're running a thread-aware Tcl/Tk build.

* Blocking event handlers are not the only way to prevent the Tcl interpreter from
reentering the event loop. It is even possible to run multiple nested event loops
or abandon the event loop entirely. If you're doing anything tricky when it comes
to events or threads, be aware of these possibilities.
