Hi
this is my first try with boost. I need an object pool, where I can 
preallocate X objects and reuse them with ability to allocate more if 
the pool runs empty and shrink my pool if needed. My questions:

1. Is object_pool suitable for this purpose?
2. Does object_pool.free() returns object memory to the pool or return 
pool's memory to the system?
3. How do I use object_pool.construct()? I didn't get the number of 
parameters requirement in the documentation 
(http://www.boost.org/doc/libs/1_40_0/libs/pool/doc/interfaces/object_pool.html)
