-/* FIXME: this delqueue module is very flawed and should be rewritten.
- First, having an array of a fixed size for keeping track of the
- unlinked but not yet deleted files is bad. Second, some programs
- will unlink files and then create a new one in the same location
- and this behavior is not supported in the current code. Probably
- we should find a move/rename function that will work on open files,
- and move delqueue files to some special location or some such
- hack... */
