Do you keep adding files to the directory while you move files out?
Yes, otherwise there are too many files in the directory and viewers, e.g.,
each geeqie (picture viewer) will use > 4-6GB of memory, so I try to keep
it around 5,000 pictures or less.

What's the rate of additions/removals to the directory?
Additions it depends, around 5,000 over a 12hr period, 416/hr, current:

atom:/d1/motion# find cam1|wc
5215 5215 166853
atom:/d1/motion# find cam2|wc
5069 5069 162181
atom:/d1/motion# find cam3|wc
5594 5594 178981
atom:/d1/motion#


If we add files to the directory while removing others we could easily
re-use the same offset for a different file.
