I've got similar complaints in the RH/Fedora bugzilla. It's hard to fix
in a portable way because of the lack of consistent select/poll
semantics across various platforms. See my previous notes about the
lack of consistent EINTR behavior and whether we should really be using
SA_RESTART.
The short answer is "don't hold your breath". It'd be nice to have a
plan for improving things though.
