Comment:

 I also observed the problem, but there is a simple explanation. If you use
 MANY std::vector objects using boost::pool_allocator, then you might run
 into this problem. This is, AFAICT, by design - the vectors are just
 deallocated out of the "ideal" order. (You should not use other std
 containers with this allocator.)

 The solution is - just use std::allocator for std::vector (the performance
 is comparable). For the rest, use boost::fast_pool_allocator.

 (There are other solutions possible, but this is a bit OOT here.)
