I have a point in my program where a timer is set up to fire as soon

I would like to collect the functions triggered between the timer
being set up and the timer firing since this would tell me what's
delaying the firing of the timer.
I suppose I can just print the probe functions but I would also like
the ability to discard them whenever a timer gets cancelled. I would
like to keep only the trace leading to the timer actually firing.
What is the best way to accumulate the probefuncs keyed on the
sequence id (0, 1, 2,...) and discard them if the timer is cancelled?
Thanks, Joel
