I do this often with TidTCPClient.  No problem sending data from,
say, the main thread while the worker is waiting to read..  Your
stack-based buffer means that the onReceive event must be fired in
the thread context or using 'synchronize' or 'sendMessage'.  If you
want to use 'postMessage' or some other no-wait queueing mechansim,
you should use a new heap buffer each time.

Your timeout seems a little short,(10).  What do you do on timeout?
