Or: don't delete foo; the keys, instead foo->deleteme();
pthread_key::pthread_key(){
inuse_count = 1;
}
pthread_key::deleteme() {
interlockedincrement(inuse_count)
if interlockeddecrement (inuse_count) == 0
delete this;
}
pthread_key::rundestructor() {
if (interlockeddecrement(inuse_count) == 0)

This prevents the race you describe with no locks.
Still, this race is actually one ieee says we don't care about IIRC,
it's up to the user to synchronise calls like this.
