I think there is a subtle difference between someone understanding that
``UDP is unreliable'' and someone understanding that the remote protocol
doesn't work across UDP.

Take for instance, TFTP. Everyone knows that TFTP uses good old
unreliable UDP but hey that still works, right? It just means that it
has the occasional hickup.

GDB's remote protocol can't come close to meeting even that expecation.
Drop a packet and the session can die.

BTW, anyone thought to try typing in ``tiny tcp stack'' in a search engine?
