I posted about his a few months ago and received no reply.  I worked
around this issue by not using the singleton allocators, but that's
hardly a solution.

This seems to be an issue with the rebind.  You're really looking for

boost::singleton_pool< boost::fast_pool_allocator_tag, sizeof( map
node ) >::purge_memory();

but I don't think there is a portable way to determine that map node
type or size.
