29471de459 Issue #13854: Properly handle non-integer, non-string arg to SystemExit

used an exit code of 1 when the argument was a string instead of zero.

59d5404bc7 Issue #14753: Make multiprocessing treat negative timeouts as it did in 3.2 
In Python 3.2 and earlier, Process.join() and Connection.poll()
treated negative timeouts as zero timeouts.  Earlier versions from
the 3.3 line of development treat them as infinite timeouts.

The patch reverts to the old behaviour.
