dump_traceback_later

faulthandler

function

dump_traceback_later(timeout, repeat=False, file=sys.stderr, exit=False, *, max_threads=100)

Dump the traceback of all threads in timeout seconds.

If repeat is true, the tracebacks of all threads are dumped every
timeout seconds.  If exit is true, call _exit(1) which is not safe.
max_threads caps the number of threads dumped.
