If you have followed the thread, then you know that I have a multi-processor
system and I don't have the problem.

There is no point in reposting scripts.  There is no point in
recapitulating the problem.  There is no point in making obvious
observations about what one would suspect the cause would be without
bothering to look at the code.

Your options are to fix the problem yourself or wait until I someday
have a system which demonstrates the problem.
