Great.

Just after reading of TBB description, they underline that this is
high-level framework, which

** hides low level OS-threads instead offering to developer high-level
concepts as Task. 

** They offer algorithms for parallel execution, e.g. Sort()
    Cool?  I have not see such things in ACE.
    I will be happy to get quick-sort which works on 8-32 CPUs :-)

** They offer containers with not single mutex but with lock per item.

---------------
I do not see problems why ACE cannot use the same ideas to become better
where it is possible. I think developers of ACE should be self interested at
least take a look on sources/design/docs of TBB.

As I see ACE is more cross-platform that Intel's TBB.
So unlikely we will switch from ACE to TBB in near time.
