Yeah.

In fact, imho, this should have moved off to the Xfree dev list a few
posts ago.. I trust the OP or someone along the line has fwd'ed this
thread to their list....

I remember this from Red Hat years ago...It's always been around, bout
time they (Xfree)fixed it.

That seems like a pretty unhelpful solution.  Say the system crashes?  
Or KDE or
X crash?  The same problem will still exist.

With this solution someone could intentionally crash your machine to 
avoid those
routines from running.  I'm not trying to put you down or anything, in 
fact I probably
know less about video related stuff than most on the list, this just 
doesn't seem like
the best way to do it.  I have no better suggestions, I'll leave this
one to
the experts.
