Of course, it definitely is necessary.

I'm concerned about _outside_ poking around _inside_.  Bad
idea.  While it's always been easy to do with mh, I don't
see a need to encourage it any further.  And I'm willing to
help make it less necessary.

Would a don't-modify-any-internal-nmh-state switch to pick
would have solved that problem?  Assuming it was specified,
of course, but compared to locking that's not a disadvantage.
And if the machine crashes while it's executing pick with that
switch, no harm.
