Don't know how to handle flushing for the block. No chance to get another buffer which returned to buffer pool when blocked on allocator_allocate.
If you go this way (alloctor that blocks), your allocator will have to 
be internal, I think this won't be a problem, You'll need custom method 
to flush, but this is simple now, you should have to chain 
flush_start/flush_stop from the pool.
