With the linked in version of nanoX's client/server, there can only be
one application, and since nanoX is single-threaded, it can never happen.
However, on the unix-pipe version, running dual processors, (which I do) it's entirely
likely that the two processes will be writing the pipe asynchronously.
There is quite a lot of literature on the business of getting multithreaded objects
to talk to each other in a synchronized fashion. Let me know if anyone's interested.
