probably a leftover from previous refactoring, server->shutdown = 1
is directly set in the cases that matters, removed ret altogether.
In the current code head, server->shutdown has been renamed
server->quitEventThread, so patch changed accordingly.

Actually in that case I think the current code is fine, the function
should exit 0 on EAGAIN, it's documented, I assume the read will be
retried by the caller, otherwise we would have used saferead() there an
internal routine taking directly care of interrupted calls.

Same thing, I guess it's intended behaviour :-)

Ah right, harmless but fixed :-)

okay

Okay, fixed, allows the test to fit in 80 columns too,
Patch for git head attached.
thanks a lot !
