[pool] Doubling algorithm

[Martin_Scheffler]

I just stumbled across an old problem:
The maximum size of new allocations cannot be limited in boost::pool.
I have a pool that grows to hundreds of megabytes. The pool doubles its
allocation size every time it runs out of free space. Because Windows wants
to allocate consecutive free space, I get out of memory errors even when my
program only uses ~500 mb of main memory. If I could limit the amount of
memory to allocate this would not be a problem.

This was already discussed here:
http://lists.boost.org/Archives/boost/2008/10/143763.php

Has anything happened since then? Is boost::pool currently maintained? Or
are there alternative memory pool libraries I could use?
Thank you!

I have solved this in the past by writing a simple wrapper class that
caps the max pool size.  I also made it not double at one point, but
found that the doubling scheme worked "better."

AFAIK, there is no maintainer.  However, someone volunteered a few
months back to make some long-needed fixes.  Not sure what ever became
of that.
