So the only things left in spin.h are the spinlock headers and

#define spinlock_destroy(lock)
I cant se why we need these abstractions. Should we nuke the whole file and
add the spinlock headers elsewhere?
Don
Ok, if you want it :)
-------------------------
remove abstraction macros in spin.h, remove the callers, and
remove the file.
