[New-bugs-announce] [issue37851] faulthandler: only allocate the signal handler stack when faulthandler is used

[STINNER Victor]

New submission from STINNER Victor <vstinner at redhat.com>:

Currently at startup, Python always call _PyFaulthandler_Init() which allocates a stack of SIGSTKSZ bytes, even if faulthandler is never used. That's a waste of memory: the stack should be allocated the first time faulthandler is used.

bpo-21131 requires to enlarge this stack size.
