Which is why I don't like to use cp for large directory copies of
100's files and 100's of GB of data.

rsync is much more functional for me.  I'd just like to get the

Maybe I will run some strace's tomorrow and see if I can figure out
why it isn't doing well with cygwin/windows filesystem caching.
