ls bug

[Kurt Glaesemann]

When doing an ls in a directory with many files in a directory that
is mounted over NFS, the ls command uses all availible memory on
the machine.  Copying such a directory with cp does the same thing.
The directory has 3594 files in it.  And the NFS server is not running Linux.
Running the command on a local directory with huge number of files, 
causes no problems.
