Yes,the memory leaks are still there.  However, I should point out that
according to MEM_INFO, no Eiffel or C memory is leaked.  But the heap
keeps growing, as shown by "pmap PROCESS_ID | fgrep -i heap".  This
indicates to me that the leak may be in GTK itself (GTK+2.4 in this case,
though I suspect the problem exists in 2.6 as well).  This may make it
hard to fix.  In my experience, every version of GTK has fixes for
memory leaks listed in the release notes.
