ssh reverse tunnel issue

[Michael ODonnell]

Since the primary complaint is that the connection "freezes"
for as long as a minute I'm gonna predict that this will turn
out not to be compression-related.  Yes, unnecessary/redundant
compression can reduce throughput but the effect would be
(approx) constant rather than intermittent and I can't imagine
it bogging things down for a solid minute.  This smells more
like a scheduling problem or maybe some transient network failure.
