Bug Description

for a pygdb backtrace.
Had to manually kill, the default stop action, didn't.
Requested info on next hang:
- grab a core before manually killing (perhaps you did this time too)
- gdb 'thread apply all bt' + pygdb's rev52 run on the core.

AFAICT, and probably stating the obvious, every thread except 2 was waiting for the GIL. Thread 2 was starting a thread and waiting on a lock to delete the current GIL state pointer. Looks like a Python or OS bug to me.
