Please see 
http://groups.yahoo.com/group/boost/files/shared_cyclic_ptr/cycle.zip.
It contains a test for cycle collection for all three collection
methods.  Only the os_collector collects the cycles, and I think
this is because it may delete a live pointee.  Please check the
code and see if I'm mistaken.
