[libvirt] [PATCH] retry poll() in EINTR case in virPipeReadUntilEOF
I saw a few messages: libvir: error : internal error poll error: Interrupted system call during daemon-conf tests. The messages come from virPipeReadUntilEOF. I think the intention is that this case should be retried. Patch attached.

ACK, definitely neccessary.
