Hi Adam,

Your code looks interesting. Though I guess we will have some problems 
to generalize the process to include boehm-gc altered thread call. If 
you look carefully to thread-impl.c you will see I've added an ifdef 
(*sigh*) to include a specific boehm includes when we want to use this 
GC (which we cannot now but will happen in a near future). The easiest 
solution is to leave the code as it is and simply disable the multi 
thread model generation if we want the boehm GC.

Just a comment...

Guilhem.
