[New-bugs-announce] [issue23886] faulthandler_user should use _PyThreadState_Current

[Albert Zeyer]

New submission from Albert Zeyer:

SIGUSR1/2 will get delivered to any running thread. The current thread of the signal doesn't give any useful information. Try to get the current Python thread which holds the GIL instead, or use NULL.

I have patched this for the external faulthandler module here:
