Not a built-in option AFAIK.

And what would we be waiting for?  If the node is locked, it's probably
because someone else is already allocating it.

There will be other candidates that aren't locked, so we might as well
try to grab one of those.  (Or if there aren't, we have to disappoint
the caller anyway).
