Integration with pytest-timeout plugin

Inizia tracciando pytest_forked/init.py, in particolare pytest_runtest_protocol e forked_run_report, attraverso py/_process/forkedfunc.py e il percorso di timeout in pytest_timeout.py. Determina se è possibile preservare il traceback del test sottoposto a wrapping e considera il lavoro necessario affinché un timeout riporti informazioni utili dal test sottoposto a wrapping invece dei soli frame di pytest-forked.

Hi, when trying to add pytest-timeout to troubleshoot a hanging test, I get the following output:

Seems that the traceback includes only pytest-forked information.
Do you know if it's at all possible to get some traceback info from the wrapped test?
Thanks.
