[Gc] GC on Darwin/OS X

I've made significant progress getting everything working on OS X.  
After fighting with the pthread_kill method of suspending the threads 
for way too long I finally decided to give my mach thread_suspend 
implementation another try. Once I fixed a few bugs in that, 
miraculously, it worked! Threads and dylibs both seem to be working 
very well. Right now my whole tree is somewhat of a mess. Once I clean 
it up a bit I'll post a patch against the latest version. I also have a 
few things to run by Hans and he seems to be gone till April 1st. In 
the mean time, I'd appreciate if anyone running OS X could give it a 
try. Here is a link to a tarball of my tree:


To build:
$ ./configure --enable-threads=posix --enable-shared
$ make gctest
Verify gctest is using a shared libgc.dylib (you'll see libgc.1.dylib 
in the output)
$ otool -L .libs/gctest

Run gctest (some debug info is still there, ignore that)
$ ./gctest

Hopefully that'll work, now do anything possible to try to make it 
break. Running "./gctest  &" 20-30 times is always fun! If you have any 
other programs that use the gc try them too.

Finally, let me know if it blows up.
