rtsig on Opteron

rtsig is an absolute piece of shit interface. Two smart people tried to
make it work with libevent and spent a lot of time working on it but never
got anywhere because it's just so horribly broken.
I thought the libevent maintainer disabled it. :/ You really shouldn't
be using it.
Just use poll/select. CPU usage will be slightly higher.
