            Priority:  major         |  Milestone:  5.3
           Component:  unknown       |    Version:  5.1.0
          Resolution:                |   Keywords:  signals, parameters
Estimated difficulty:                |
-------------------------------------+-------------------------------------
Changes (by Sebastien Marie):

 * keywords:  signals, parameters, load => signals, parameters


Comment:

 the testcase could be simplified to not depend on (load).

 {{{
 $ cat hup.scm
 (cond-expand
  (chicken-4
   (use posix))
  (chicken-5
   (import
    (chicken base)
    (chicken process signal)
    (chicken process-context))))

 (define param (make-parameter 42))
 ;(param 42)

 (set-signal-handler!
  signal/hup
  (lambda (signum)
    (print "reloading")
    (param 4)
    ))

 (let loop ()
   (print (param))
   (sleep 1)
   (loop))
 }}}

 when {{{(param 42)}}} is uncommented, the code works as expected, and the
 signal handler properly change the parameter.

 else the parameter continues to return {{{42}}} value even after signal
 hander called {{{(param 4)}}}
