If you are really typing a CTRL-Z here, then you are suspending the cat
which is creating the foo.  That means that cat would be keeping the foo
open, which means that cygwin would be using "unlink-on-last-close"
semantics.  The UNIX/linux/cygwin method EOF character is CTRL-D.

Otherwise, I can't duplicate this behavior on either XP or W2K on either
a FAT or a FAT32 disk.

Nope.

My WAG is that you are running some other software running in the
backgroundwhich is interfering with normal windows behavior.
