I'm slightly embarrassed that I didn't see the call to clear_stack
from malloc... 

I just adding a call to clear_stack at each SCM_NEWCELL. Guess what:
it does help on heap size but it is incredibly slow:-(

In the non-threaded case, Boehm seems to do some clever optimization
using stack tide marks. Given the discouraging results of the
brute-force approach, I don't think I'll pursue this any further.
