Well, keep in mind I'm not arguing for events to be processed as fast as
possible... there is still a game imposed delay inherent to every action
(save out-of-game actions, like "score", or "help!"). I know you've
mentioned a few times, JC, that kookey idea that humans shouldn't be
waiting on computers... ;)

I'm not sure that I like these kinds of filters, etc. The computer trying
to figgure out what I am up to seems prone to error. Heck, other ppl
trying to figgure out what I'm up to is prone to error. I think the
problem you are trying to solve is, when the user types 'eat sandwhich'
whilst diggging the panama canal, they most likely mean 'pasue for a while
to eat this sandwhich, then get back to work'. You want to automate that
returning to work, because forcing them to re-type the 'dig panama canal'
command leads to tedium, and possibly some confusion on the parser's part
(what do you mean, dig panama canal? it's half built already!).
Why not offer a "pause to/for" operator, and push the resposibility of
realiing theyw ant to continue the action after a small break onto the
user? This greatly simplifies the problem of event interruption, as you
don't have to worry about wether the player intended to continue the
action or not.

The downside to this, as Vadim pointed out in a previous post, is that you
trade a scarce resource for more CPU cycles spent on event scheduling,
etc. Leans back towards the age-old memory v. computation cycles
tradeoff.
I snipped the rest of this message to be handled in a seperate response,
as it is wandering away from the topic of event handling some... and I
have a meeting in 20 minutes and prolly can't finish responding before
then. ;)
