You can only use the socket in one thread at a time. You can pass it on 
to another thread, but you will find yourself with weird bugs if you do 
this a lot.

You haven't given enough information to say if this is a problem for you 
or not. If the threads just send stuff over the socket, then implement 
this with simple message parsing to the thread that have the socket. If 
the threads handle incoming messages (which I wouldn't expect, since 
you're using timers instead of handling incoming data signals), the 
answer depends on whether your protocol allows out of sync answers or not.
