send ___ to me in ___ sec

[David Vaughan]

Dar has covered much of the issue but there is still one thing that 
puzzles me about your question. It implies that the "currently running 
scripts" are running in an order which is unknown to you, or else you 
would simply call your clean-up routine at the end of your last script. 
I assume the relevant scripts are your calls, not Rev messages. You can 
guarantee this by trapping the last Rev message (e.g. deleteCard) and 
sending from that, or using the preOpenCard message for the next card, 
which occurs after your other card has been deleted.

If you can not guarantee which is your last running script your options 
include:
- sending in a suitably long time.
- as Dar suggests, decide your send time by looking at the currently 
pending message list.
- having the clean-up script itself check the pending message list and, 
if the list is not empty, send itself at another short interval then 
exit.

David
