I'd first enlarge "files =" to 40, and see if that affects the number
of files ar is able to process before it barfs.  (The fact that it
currently barfs on the 22nd file could be explained by inheriting some
of the handles from the parent process.)

I'm not familiar with 'ar's sources: does it need to keep files open,
or can it close a file after it has copied it into the archive?  Might
as well look this up in the sources.
