Where should I put this?  In config.h?

I believe it would work.  OTOH, the unlocked-io package sounds to me
like something you should opt-in for, not opt-out from.  So couldn't
packages that want the unlocked-io optimization go through extra work,
instead of forcing packages that want to be thread safe to go through
extra work?
