Cygwin mount "notexec", what does it really do?

[Mark Liam Brown]

Greetings!

I tried to benchmark Cygwin mount "notexec" compared to "exec" by
building bash in a loop.
So far I do not see any performance differences, and putting a Cygwin
binary like ls or bash into a folder mounted from X: to /cygwin/x with
"notexec" still causes those binaries to be executabe.

So what does "notexec" really do?
