I tried it on a few files that should be 100% safe and things seemed to work
but then I got enthusiastic and tried it on a whole bunch more.  I could do
an 'ls' in bash.  It displayed the files and then died.

You're probably right, though.  It would be interesting to benchmark a cygwin
built with and without the option to see if there was a noticeable change
but I'm not going to do that anytime soon.
