Hello Vicente,
thanks for your response - I'll remove lazy and adaptive strategy and release 
the new version in the boost vault soon.
Please note that the work-stealing is not fork-join as you requested in some 
of your previous emails (so please don't be disapointed).
For fork-join two possible strategies are possible - one like in JAVA (from 
Doug Lea) which blocks in pool::submit() until the main task and its 
sub-tasks are finished - the other solution would require stack switching as 
it is provided by the coroutines lib in the vault.
I would prefere the stack switching solution but it seams to become a complex 
implementation.
regards,
Oliver
