rpc.idmapd: Dies with 'I/O possible'
We have had problems on some of our machines (all Fedora 14), where
rpc.idmapd used to die with an `I/O possible' message at (basically)
random times. A strace suggested the issue being in nfsopen() where a
signal type is reset before notification is disabled; a signal at just
the right time might be the cause of the problem; see
https://bugzilla.redhat.com/show_bug.cgi?id=684308
