Ok. My fault, as always...

After checking that another program I had written worked with Poll and
seeing what was going on with ethereal, I found out that I forgot to
flush the socket data. Doh! :)

After that, Poll worked from the first data exchange as it would if I
had done it right the first time.


Btw, after checking Mono sources, Poll wasn't working but Read was, as I
previously stated, because Mono code wisely flush any pending writes
before doing read. Thanks Mono for doing the right thing!
