Yes, that's what I meant.

If I said something that amounted to that, it's not what I meant. I don't know
what I might have said that led you to believe that's what I meant. Which is not
to say that, in my confusion, I said nothing that amounted to that.

I admit, though, that when I first suggested that nmh locking be brought out to
an external program, I thought that nmh locking was much, much simpler than it
actually is. Had I known how complex nmh locking is (multiple interacting locks
etc), I probably would never have made the suggestion.

I also admit that I don't understand why nmh locking has to be so complicated,
but I leave that issue to my betters.
