With gcj our root set is way, way too big.  Fixing this is at the top

Funny you say that. The first thing I have to do when I build gcj is add #define LARGE_CONFIG to boehm-gc/include/private/gc_priv.h so that I don't get the dreaded 'too many root sets' error because libgcj's GC insists on seeing *all* memory roots even ones that have absolutely nothing to do with the java heap.

I'm embedding a gcj-compiled shared library in a python-based process. There is no memory outside of what is allocated by that one shared library that libgcj's GC needs to worry about.

Andi..
