[Spread-users] Socket Timeout

[Ryan Caudy]

Alberto, everyone else on the list who uses the Java library:

I've attached a patch for SpreadConnection.java against the 3.17
branch head, which should be the same as the 3.17.3 version.  I think
I've addressed both of Alberto's outstanding problems, but I've only
been able to test the changes that fix the connection-rejection error
codes (because of strange behavior when User tries to install a
listener).  The change to avoid the listener race condition is
untested, but simple... I simply added a call to join with the
listener thread after setting the flag to terminate it.

Alberto, please let me know if this solves both of your problems, so I
can commit the changes.

Cheers,
Ryan
