After some tinkering I think i've found the problem. I've tested this with
GNU Emacs 21.2.1
The problem was that the "zone" function calls "zone-when-idle" with
"zone-idle" as argument for the seconds. This doesn't work to well when
a user chooses to invoke the "zone-when-idle" function and pass the
number of seconds to it.
What happens when doing "M-x zone-when-idle" and entering 60 seconds as
idle time is this :
(1) "zone-when-idle" sets up an idle timer which is invoked after 60
(2) After 60 seconds of idle time the "zone" function is actually
(3) At the end of the "zone" function the "zone-when-idle" function is
called with an argument of "zone-idle" seconds (which is still at
the default value of "20")
(4) "zone-when-idle" sets up an idle timer which is invoked after 20
seconds of idle time.
(5) Now, after 20 seconds of idle time the "zone" function is invoked
Obviously not good, the user would expect the idle timer to trigger
after 60 seconds, not 60 the first time and 20 all other times.
There are a couple of solutions to this problem :
(1) When using the "zone-when-idle" function also set the "zone-idle"
variable, like :
(setq zone-idle 180)
(2) Explicitely set the "zone-idle" variable in the "zone-when-idle"
function (use the value the user passed, the "secs" variable)
(3) Remove the call to "zone-when-idle" at the end of the "zone"
functions, if the idle timer works correctly it should repeat the
invocation every "secs" seconds anyway.
