Quite. My solution is almost identical to yours:
Event {
for each object in biglist {
log event XXX.modify (object)
}
}
When the event executes it adds events for all the objects that need
to be processed to its exit criteria. When it then C&C's those events
are added to the Dispatchor and are processes as per normal from there.

Umm, no, I'm not. I maintain that the two have different curves under
load and contention that are incredibly dependent on the exact loading
characteristics, and that I am satisfied with C&C's performance
characteristics. C&C is not a godsend. It has its own problems,
especially in recovery of process stack state, and in ordering.

Quite. I expect it will be much more platform, process model, thread
model, implementation etc dependent as vs model dependent.
