Correct. The exception would be fore timed events where you have "background execution" set to "Yes", but that can only be done for native programs (e.g. jsexec), not for the direct invocation of a script (e.g. binkit.js).

Yes.

And for ever foreground "Running" log entry there should be a corresponding log entry like this:

BINKPOLL Timed event: BINKPOLL returned 0

Giving you an indication of exactly how long that event took to run to completion.

Looking at the CPU utilization of *threads* of sbbs would give you a good indication:
http://wiki.synchro.net/monitor:index#threads

The threads are named and events are run in the "sbbs/events" thread.

Well if you figure out how to reproduce the problem, let me know.
