I found a killed (BUG-FIX #2): It only existed in the Low-Level IA-32 
Abstraction C API/ABI. It had to do with the fact that the 
g_spinlock_ia32_table_mem, g_spinlock_ia32_table global variables and the 
spinlock_ia32_libinit(void) function were declared static. These dosen't 
work well with multiple translation units; you can get multiple copies of 
the table per-process. I added the 'spinlock-ia32.c' file to the library in 
order to keep a global copy of the locking table. Of course, this particular 
bug didn't show up before because all of my initial test applications only 
consisted of a single translation unit!

I had to add this file:

http://appcore.home.comcast.net/vzoom/refcount/spinlock-ia32.c

And alter this one:

http://appcore.home.comcast.net/vzoom/refcount/spinlock-ia32.h

You should probably re-download:

Thank You.
