I don't understand.  Why would you expect 'f' to mean anything?  If
I do "kill f" on linux I get:

    % kill f
    kill: illegal pid: f

I think you probably mean 'kill -f'.

Hmm. That seems to be broken currently.

It's pretty simple:

      pinfo p (pid);

The external_pinfo struct is intended for external use.  It's not
intended to be called from inside cygwin.
