ps output isn't very informative, although it shows a large virtual
size.  The real information came from looking at /proc/PID/maps and
/proc/PID/smaps which show very large numbers of 8MB anonymous
segments, which could be caused by malloc never being freed (or just
fragmentation - I'm not clear right now).
