I installed TBB this morning on my system and will try to have a look. I
know it is also a framework to deliver threading related frameworks.

A lot depends on what you want to accomplish. For probably most apps it is
not interesting to lock per item, but lock at a higher level, locks are
expensive.

We are of course interested in learning of other projects, but the biggest
problem as always is time. We do welcome patches from the user community to
improve/extend ACE.
