Actually, I think that getting chroot to work would be trivially easy in
cygwin as long as it is understood that it would only affect cygwin
processes and not any other Windows processes.

Since cygwin.dll already performs translations on all of the pathnames
it receives, "all" you have to do is add one more level to translate
the first slash to whatever you've chrooted to.  This information would
have to be inherited by all of the child processes but that too is doable.
