In use by a particular process, or by the system as a whole? The number
in use by the system as a whole shouldn't increase due to file descriptor
leaks across forks, since the nnrpd child still has the same file
descriptor as the parent.

What overview method are you currently using? I think Clayton's code had
various schemes to share data between the daemon nnrpd and its children
that may not work when innd is spawning nnrpds.
