Atomic operations from user-space?

Hi,

I'm trying to debug some mutex code (or more correctly work around some
of glibc's mutex breakages with real-time scheduling). However I'd like
to do some reference counting and I can't think of a good way to do it
in user space.

glib-2.4.0 seems to promise atomic operations but a) I can't get it to
build for sh and b) looking at the code it seems to use mutex's for
arch's it doesn't explicitly support.

Anyone got any ideas?
