i might be inclined to rephrase that as "due to xnest being unstable and buggy,
i decided to change software unrelated to its real stability issues just to
avoid the problem, and not to help fix it".

if xnest crashes - guess what? it's xnest's fault.

i use xnest often - and it works well most of the time, has some weird behaviors
and has some severe performance issues.

on the other hand E isnt perfect - it crashes too :) but thats not the problem
at hand :)
