Hi Antonie,

Can you check the patch on Win2000? and see if the random
failures go away. (The sleep time may need to be increased).
If the random failures go away, I think the change
should be committed.

I am not to sure if it is a good idea to put
the delete() hack^Wmethod in FileUtils, but perhaps.

Cheers,
Peter
