Can I use this one?

"Did you happen to notice who you're responding to?"

If you add this code then you have to sprinkle understanding of it to
every function which manipulates files on the disk.  You'll have to
detect when it is possible to use it and when it isn't.  You'll be
adding overhead and, unlike the horribly ugly, and terrifically slow
(and did I mention that it reduces the number of characters available
for filenames! Yes! It's true) code for managed mode, you'll be adding
code almost everywhere cygwin manipulates files on disk.

Another good point is that managed mode reduces the file name length.
Don't forget about that.  Don't *ever* forget about that.
