Public bug reported:
run this program:
import signal
import gtk
signal.signal(signal.SIGCHLD, lambda *args: None)
gtk.main()
Send it SIGCHLD. CPU usage will go to 100% as it goes into an infinite
loop failing to read from a pipe.
Upstream bug report is https://bugzilla.gnome.org/show_bug.cgi?id=640738
with a patch to fix the issue.
This shows up on Maverick, at least.
