i think the comment above the function is important
"we use one lock per directory".  it's been a long time since
i worked on nupas, so i don't recall all the details, but
iirc, imap4d relies on having one lock per directory.

of course, nupas takes pressure off the directory lock
by using mdir format, which doesn't require a lock.  the
indicies are lock files themselves.

under what circumstaces did you find a problem?
