Really?  I thought that a tail call optimization essentially
turned a return into a goto (plus some variable (re)binding).
What architectures can't deal with that?  Something funny about
ABI for activation frames or the like?

Just curious: don't let me stop you from picking an in-kernel
sort routine one way or the other :-)
