STINNER Victor <vstin...@python.org> added the comment:
> Signal handling in Python is asynchronous. > https://docs.python.org/3/library/signal.html#execution-of-python-signal-handlers See my previous comment: "CHECK_EVAL_BREAKER() matters for signals, but also multithreading (drop the GIL), asynchronous exception and pending calls." If a thread executes a function which only uses opcodes which don't call CHECK_EVAL_BREAKER(), I understand that it can eat more than its slice of 5 ms, see sys.getswitchinterval(): https://docs.python.org/dev/library/sys.html#sys.getswitchinterval So it's also a threads scheduling issue, no? ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue46465> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
