PHWinfo - Afficher un message - UW (on AIX) IMAP server occasionally stuck waiting for mlock helper output

I would have expected, if the mlock process died, that the imapd process
would have gotten an error from the read() on the pipe. But then again,
you said that you're using AIX 4.3. It is no small joy to me that our
last AIX systems have just been retired... :-)

Does the attached timeout code ?
