Re: [libvirt] the POLLHUP envet for a pipe descriptor is the cause that the libvirt_lxc costs 100% cpu usage.

I found the poll in virEventPollRunOnce (vireventpoll.c), a POLLHUP

don't know what to do netx , to mask the hangup event or to do something to
handle the hangup event , what to do ? Is it a bug or something ?
Obviously there is a bug, since we should never go 100% CPU burn. We are
already handling POLLHUP though - it gets mapped to VIR_EVENT_HANDLE_HANGUP
Not sure why we continue to burn cycles though.
