Candidate for the FAQ?  What version of X?  Patched to what level?
What version of Motif?  What OS?  X11R3 and Motif 1.0 both have serious
memory leak problems.  X11R4 and Motif 1.1 have cured most of them,
but there are still some remaining.  Have you patched up to fix-18 on 
X11R4; serious leaks abound in XtDestroyWidget if you have not.

Finally, under any version of UNIX, you will *never* (never say never) see 
a process size get smaller.  That's just the way malloc is implemented.
