[on the behavior of unlink()]

	I think that you'll find that UN*X (unlike other systems) is
happy to remove a file even if it's in use.  The caviat is that the
space remains in use until the file is closed by all other readers and
writers.  One could use this information to create a very large (but
very volitle) temporary storage space that is hard to find.

	You might notice that the function is 'unlink' not 'delete'
