[issue20601] tracing and tests that raise an exception in a SIGALRM handler

[Xavier de Gaye]

New submission from Xavier de Gaye:

After an alarm handler raises an exception while a tracing function is being invoked and when this exception is not caught by the tracing function, the call_trampoline() function in sysmodule.c returns NULL and its caller, trace_trampoline(), removes the trace function.  Therefore, tests that raise an exception in an alarm handler should use the support.no_tracing decorator as it is done in test_io.py at check_reentrant_write().

Patch attached.
