I would think so since there shouldn't be anything unaccounted
for on the wire. I haven't seen the VB_NETWORK message ever with
this version. Since bytesAvailable is always 0 it's only a gain
of the one sleep really. I'm not sure if there is the possibility
of a partial block after an error or something like that.
