I agree :)  Thanks for the patch!

The patch goes in a direction that I'm a bit hesitant about though --
this command-line processing is getting a bit intense.  Would it be
possible to add a #:cleanup? argument to the spawn-server function
instead?  My only doubt would be whether all threads unwind when the
program ends.  (And if they don't, is that a bug?  I am not sure but I
would guess so; dunno.)
