reliable receive is ciritical for WRITEs. Even if the WRITE is executed

I keep hearing this word "reliable", it means something very
different for TCP over a transport like IP than it does
for the SCSI layer.

It is, in fact, the whole difficulty of implementing iSCSI:
being able to cope with this difference in expectations.

All I can see is that the SCSI layer's timeout is inappropriate
for something like iSCSI, not that TCP or networking needs
to change in some way.
