Tricky fix. If we were waiting for an oplock break response message from
another smbd and an incoming SIGUSR1 message arrived we'd break out of
the wait early - as we have to use sys_select() to wait for an oplock
response message, not sys_select_intr() (which ignores EINTR errors)
because of the real time signal kernel interface.
Jeremy.
