The philosophy was that we could get real ownership and real executable
bits and real UNIX permissions.  I also thought it would be nice to have
a multi-user NT system where people couldn't routinely kill each others'
processes.  I asked Corinna for this and she spent a lot of time on it.

I can understand why you don't want to use it.  Just turn if off.  If
you still are having problems then they're probably not due to ntsec.
There's probably a bug in cygwin from something *I've* done.
