Fluids vs. Threads and Processes

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

As of scsh-0.6.2, this

(let ((x (make-fluid 'foo)))
  (let-fluid x 'bar
    (lambda ()
      (run (begin (display (fluid x))))
;      (fork-thread (lambda () (display (fluid x))))
      (display (fluid x))
      (newline))))

prints "foobar", or "bar" and "foo" with the FORK-THREAD instead of the
RUN clause.  While this may be a feature, it's not an evident one, and I
would like the S48 and Scsh manuals to point out the interactions of
fluid bindings and threads/processes.  Presently they don't seem to do so.
(I didn't scrutinise them thoroughly.)
