Threads fail to join in 1.0.8

[Jon Wilson]

I have some code (below) where I create two threads, they establish the 
client and server ends of the socket and recieve a string append to it 
and send it back. However, when the run method completes, the threads 
call their finalize method and print as expected. However, in `main`, 
the threads fail to join. Have I done something wrong? Is there a known 
issue with this?
Thanks.
