Yes, it was the differences between the i386 and x86_64 versions that
made me notice this problem. The ia64 version is in C, so looks safer.
Ideally there would be a common C definition - the only arch-specific
part should be the locked cmpxchg, unless this lock is likely to be
taken/released so often that it's performance critical.
