Hmm, interesting. If you'll recall, the start of this thread was a
proposal to change our backends' handling of SIGCHLD from SIG_IGN to
SIG_DFL (and get rid of explicit tests for ECHILD). I didn't quite see
why changing the handler should make a difference, but above we seem to
have the smoking gun.
Which kernel, and which version, is the above quote from?
