How can this happen? Are you saying that a signal handler may delete the
process from process_alist? Which signal handler can do that?
I do think there's a leak but it goes like this:
- catch the SIGCHLD signal
- start processing delete-process, which will add the PID to
deleted_pid_list even though the signal has already been caught so the pid
won't get a chance to be removed.
I guess we could check the process's status after adding it to
deleted_pid_list, to catch this case.
