Sorry too,
We have been surprised by our first test on a multi CPU engine, after 
one year of development without big problem (only a tee problem and 
rsync not very usable (now using robocopy instead)). And now we are 
close to the delivery on 3 Multi CPU Xeon. But probably like you, we 
have only mono processor PC, Pentium 3, Pentium 4 and Athlon XP.

I know that threaded applications are difficult to develop. I think you 
are our chance to correct this.
I can do test for you, but I can't give you access to this system !

I'm going to bed, thank you.
