bug#35531: problem with ls in coreutils

[Viktors Berstis]

When running "ls" or "ls -U" on a windows directory containing 50000 
files, ls takes forever.  Something seems to be highly inefficient in there.

This is for the 64 bit version build 4/20/2005 11:41AM.  The exe size is 
180736 bytes.

Thanks.
