In-Reply-To: Linus Torvalds's message of Saturday, 8 February 2003 18:33:06 -0800 <Pine.LNX.4.44.0302081826230.7675-100000@home.transmeta.com>
There is definitely something after that patch. gdb is broken in ways that
are being mysterious to me, and now zombies with ppid 1 are sticking around
forever. With that patch, do:
bash$ (sleep 2 & echo zombie $! ; exec sleep 10000000) & sleep 4; kill -9 $!
[2] 1220
zombie 1222
bash$ ps l1222
[2]+ Killed ( sleep 2 & echo zombie $!; exec sleep 10000000 )
F UID PID PPID PRI NI VSZ RSS WCHAN STAT TTY TIME COMMAND
0 5281 1222 1 15 0 0 0 wait4 Z pts/1 0:00 [sleep <defun
Such zombies seem to stick around forever. I must have managed to break
the normal delivery of SIGCHLD to init, but right now it's a mystery to me how.
