This also makes it very hard to track down memory leaks in non-GC programs.

If you're using a recent GCC (3.4 or later) then you can disable
chunking and force STL to call malloc() for every allocation by
defining the environment variable GLIBCXX_FORCE_NEW.  Some earlier
versions had slightly different methods.
