#32 When logger output FD blocks everything blocks

The logger’s output FD has to be non-blocking. Else dprintf(FD,…) will block forever freezing all processes trying to log (all of them…)

Including stderr if --verbose option given !

The bug can be reproduce on stderr using --verbose argument, screen and siege. Entering in copy mode for a long time makes pyfcgi wait & freeze.

Syslog function logging to stderr continue to block all processes when passing in screen copy mode…
