GC leak?

I ran the latest Mercurial XEmacs under valgrind for awhile tonight, just because I really enjoy using such a slow editor. :-) When I exited, the leak check reported some lost blocks; i.e., memory that was malloced but not freed. The leaked memory looks to be mostly Lisp objects. Does this imply a garbage collector leak? Here are the relevant entries. ==6361== ERROR SUMMARY: 14794 errors from 25 contexts (suppressed: 52 from 1) ==6361== malloc/free: in use at exit: 26,271,417 bytes in 18,992 blocks. ==6361==
