proc object missing

[Rolf-Thomas Happe <rthappe@mathematik.uni-freiburg.de>]

Scsh 0.5        ; under Irix5.3
> (apply +
         (map (lambda (filename)
                (length (run/strings (co -p ,filename))))
              (glob "./RCS/*.c,v")))

;; Now some files are checked out --> stdout (I dismiss the
;; notifications by co). Yet:

Error: Child pid mysteriously missing proc object.
       14098
(Enabling interrupts)


Which is what I want to report. This error doesn't show up 
each time I run the above piece of code, nonetheless it is
reproducible.
