Description: This works around a gc.isenabled/gc.disable race condition in the 2.7 subprocess module by using a lock for the critical section. It'll prevent multiple simultaneous subprocess launches from winding up with gc remaining disabled but it can't fix the ultimate problem: gc enable and disable is a global setting and a hack. Users are strongly encouraged to use subprocess32 from PyPI instead of the 2.7 standard library subprocess module. Mixing threads with subprocess is a recipie for disaster otherwise even with "fixes" to ameliorate common issues like this. https://bugs.python.org/issue27448
