Hi,

This really needs to be added to an FAQ.  GDB's remote protocol doesn't
work reliably over UDP.  There are many cases where it is stateful
(assuming that a packet won't get duplicated).

Once the protocol is sorted out (perhaphs making it stateless) a udp
implementation would be accepted.
This patch, or variations of it turn up so often, I'm actually highly
tempted to revisit this ``policy'' and simply commit something.  A
banner message reporting that the feature isn't considered reliable when
someone tries to use it being part of the commit :-/
