The old native (non-cygwin) port of zsh would somehow detect if it was about to
exec a Windows app, and run it as a background process, thus returning a zsh
prompt immediately.  Could something like this be added to cygwin bash/zsh?

This was very useful.  With the cygwin zsh, I often find myself invoking a
Windows app and not being able to get back to the shell window without first
terminating the Windows app.

It is true for any part that Windows programs do not understand cygwin signals.

There is no way to reliably suspend a Windows programs.
