To clarify Tim's oracular answer, the last time it was tried there was
a significant performance hit.  Patches for 1.5.2 are at   
http://www.enme.ucalgary.ca/~nascheme/python/gc.html, so you 
can experiment with them.  The Boehm package is also some awfully
hairy code, so porting it to new platforms would be painful.
