number keys store JID as val, not list of size one

Denver Gingerich created 9 years ago

This is for compatibility with jmp-register commit f7ee1fe (whose code
is not yet active), and for general simplicity and correctness.  We
can now use SETNX to mitigate races rather than set-then-check-length.
