[plt-scheme] Web server pid

Greetings.

Is there a straightforward way of finding the (PLT) web server's PID  
('straightforward', here, in the sense of 'less nasty than grepping  
`ps`')?  It's the sort of thing I'd rather anticipate seeing in  
the .../log file, or in a .../run.pid beside it, but there's nothing  
there, nothing obvious in web-server/private/launch.ss, and no  
mention of it that I can see in the web-server docs.

Alternatively (for this is the point), is there some command-line  
alternative support for shutting down a particular server?  Again,  
there's nothing obvious sitting alongside plt-web-server-text.

Thanks for any pointers.  Best wishes,

Norman
