debugging Xlib: Maximum number of clients reached

[Alan Coopersmith]

That error really means "your X server ran out of file descriptors < 256"
(or whatever value MAXCLIENTS is defined to in your build), so the first
debugging tool would be something like lsof to see how many files your
X server has open and what they are.   This could be from clients using
too many MIT-SHM segments or something like that.
