Hello,

as I wrote the code, I know how it is implemented and I can tell you that 
Felix's suggestion should work unless you fiddle around manually with the 
contents of the scgi:resources parameter :-)

Just do something like

    (require-extension (srfi 18) scgi)

    (define scgi-server-thread
      (make-thread
        (lambda ()
          (scgi-server #t))
        'scgi-server))

    (thread-start! scgi-server-thread)

in csi and continue to use the prompt normally.

I remember faintly, though, that under some operating systems the standard 
input port in csi is blocking, causing background threads to run only 
while csi is not waiting for input, which kind of defeats the whole point 
of this exercise... If you experience such problems, you may want to give 
the nbstdin egg a try.

cu,
Thomas
