Another modification I was thinking of was using the allocator from the 
conservative
collector of cmm (ftp://ftp.di.unipi.it/pub/project/posso/cmm/cmm.tgz). 
 I figured
it could be used to enumerate all the allocated objects (much like 
iterating
through cyclic_ptr's recycler's handles).  In addition, since this is a 
conservative collector,
it would be easy to check for any leaks.  What do you think?  Also, it 
could be used
to eliminate the need for a weak_ptr count (as mentioned in my earlier 
post about "conserve+
shared_ptr advantages.")
