Sure, go ahead and create a bug for it.  We can make the change for 4.6 if we
make it safe.  By the way, changing configure.ac is not a problem, we can do
that, particularly if it makes the change safer. ;-)

It could make the change safer - we could check that spinlocks are available,
and use them if so; if not, we just fall back to using a standard mutex, which
is slower but works on all platforms.

Thanks
