Killing timers and buffer local variables

Killing timers and buffer local variables

[Lennart Borgman (gmail)]

If a timer is referenced with a buffer local variable and the 
corresponing buffer goes away it is quite cumbersome to kill the timer 
if it is a periodic timer.

How about adding a self referencing functions for timers to make this 
easier, something like (this-timer)?

That's a good idea.  Patch welcome,

PS: It'd be better to use the `timer-' prefix.

That was a fast one ;-)

Maybe it is sufficient to document this in

   (info "(elisp) Timers")
