The prox_recur__crc__    class had a serious bug in the operator=.
The bug could have lead to isolated cycle; hence, memory leak.

The revised code also corrects what I think is a bug in
Lin's cyclic reference counting algorithm (see crc_names.hpp
[JL96] reference).  Briefly, the bug is caused by freeing
a cell while a pointer to it remains in the control set.  The details
are in the crc test driver.

I'd appreciate any corrections.
