Subject: [Boost-users] custom allocators Re:pool_alloc

I am not understanding the use of pool with std::set. i.e. the
release_memory() function referenced in last example shown on:
http://www.boost.org/doc/libs/1_42_0/libs/pool/doc/interfaces.html
seems to do nothing.
I call GetProcessMemoryInfo() and don't see any change after the set
has gone out of scope.
maybe someone could relate what happens when set goes out of scope and
release_memory() isn't called versus set goes out of scope and
release_memory() is called.
I want to do something like:
1.std::set<unsigned int, std::less<unsigned int>,
boost::pool_allocator<unsigned int>> v;
2. for(int i=0; i<(K); i++)
{
v.insert(i);
}
3. use v
4. release_memory() on v //dump all set elements in one action
5. repeat 1-4 with a new set
