This seems easy to fix inside `closedir'.  Should I?

If `readdir' reads the entire directory, we *do* close the handle, since 
`findnext' calls the necessary LFN function when it gets ENMFILE.

The problem, it seems, is when you `opendir', call `readdir' several times, 
and then don't read any more directory entries.  These cases are usually 
rare, but I guess they could happen.
