Has anyone successfully used a bpf in nonblock mode?  The manpage 
states that an ioctl BIOCIMMEDIATE is necessary to switch from
block (default behaviour) to nonblock.  

The ioctl in the code I'm working with seems perform the switch without
error, however when I go to use the device I get

EAGAIN errno 35  resource temporarily unavailable
