What is the recommended way for a X program to receive
data from another program?  XtAddInput() seems to be the
only Xt supported way and that is biased towards sockets (I think).
Does SVR3.2 (386) have "real" sockets??

I would prefer to use message queues but when I go from using
XtMainLoop() to using XtPending(), XtNextEvent(), XtDispatchEvent()
plus a non-blocking msgrcv(), the performace of the user infterface
drops significantly.  Do I have to wait for Release 4 to avoid polling?
