We have an HP 9000/835 running 3.01 HP-UX and HP's latest release of X11. We
have written software which runs fine on Sun's (with MIT's version of X11,
R2 and R3), a Tektronix 4319 running their version of X11 R2, an Apollo
DN3000 (with MIT's version of X11, R2 and R3), a MicroVAX II (with MIT's version
of X11, R2 and R3), and an HP 9000/360 running 6.2 HP-UX and HP's latest release
of X11. Our software needs the Athena Widgets library and since HP's X11 
doesn't supply them, we built it (and the X toolkit library) from X11 R3
sources from MIT.

This works fine on the HP 360, but if we set our DISPLAY to unix:0 this
sometimes causes our programs on the 835 to hang. They run fine if we
rlogin from another machine or if we set the DISPLAY to `hostname`:0. The
routine it hangs in is XWaitForWriteable.

Has anyone else seen such a problem? Is this a bug in HP's code? Could the
addition of MIT's libraries be causing such a subtle problem? Any work
arounds or ideas? Any comments from the folks at HP?
