Also u can put a load of print(f/ln)s in the client
and server stuff to see what's going on.
Create some logs and pick through them.
This (crude) method is usually the best
for multithreaded stuff.
Beyond that, start write test harnesses for each side
of the socket, to see whether your problem is client
or server side...
Is you client thread safe? (synchronized)
