recvfrom_zcopy in epoll_wait loop

[GoogleCodeExporter]

In epoll_wait loop with multiple FDs registered should I call recvfrom_zcopy 
once only?

Otherwise if there is a continuous stream of UDP packets incoming it always 
returns recvfrom_zcopy > 0 and I never get any chance to get to the other FD.

See attached file stest.c - line #91. Is it correct (provides optimal 
performance) to attempt to receive only once?

Thanks
