I tried the phtread example from  but even with some tweaking is does
not work at all.
This is a multiprocessor system, with moderate load.
As far as I understand the matter, it can only work if both threads
share the same cpu cache, otherwise the counter variable is either never
up-to-date, or has to be fetched and stored from/to memory, which is way
too slow for this purpose.
Any suggestions ?
