[boost] [pool] block_ptr

Hi Boost... long time, In my memory manager: https://svn.boost.org/svn/boost/sandbox/block_ptr/boost/detail/block_base.hp... You will see the usage of: boost::singleton_pool because of a required is_from() function call. But I just came to realize there is a pool::is_from() function: http://www.boost.org/doc/libs/1_49_0/libs/pool/doc/html/boost_pool/pool/inte... Is that function new or in 2011 I overlooked it? If so I will make the change ASAP as this is a nice class. Regards, -Phil www.finitetheory.com
