No it is not the lib from http://threadpool.sf.net (I was refering to 
boost.threadpool in the boost vault - > now replaced)!

The benefit above boost.threadpool is that boost.task implements the proposals 
currently discussed on the mailing list from the C++ standard 
committee's Library Working Group.

Another point is that you can execute your task by different async. executors 
(which can be the default thread-pool, a customized thread-pool -> priority 
scheduling, in a new created thread, as a sub-task or in a completly different 
executor provided by yourself).

AFAIK -  the implementation from http://threadpool.sf.net doesn't provide a 
working future implementation nor does is implement work-stealing (including 
sub-tasking) or task interruption.
Boost.Task provides this functionality (it uses the future implementation from 
Anthony Williams which will be part of boost soon).
