I think you just have to deal with this possibility at your level.
This type of thing is just inherent in network programming: without an
explicit message back, you don't know if any given message has really
been received.  The exact same thing could happen with TCP for
example: just cut the cable after a message has been received but
before the ACK has gone back the other way.
