In theory, the process is only terminated if do_raise() returns true; that only happens if there is no signal handler set for sighup.

If there is a signal handler set, it gets called by do_raise(), whence it has as long as it decides to take, and sig_terminate() is never called. There is no sense in adding a Sleep 950; (which is a little under a second not 9.5 seconds) anywhere.

In reality, I can't get a sighup signal handler to ever be invoked even on 5.18. I run vista, and I never see a dialog prompting me; nor is there any delay 10s or otherwise between killing the process and it disappearing; regardless of whether I've installed a signal handler for HUP.

I'm not really sure I understand your motivation for meditating on this; but I think you need to do a lot more reading and experimenting.
