Edward,
you're a star! I'll grab the snapshot and check it out.
Thanks for the super-quick turnaround.

OK, I've checked in a fix to make fireAtCurrentTime() thread
safe (I hope... threads make me nervous...)

number of threads and the answer was to wrap the firing in a change
request. At the time Edward Lee explained that this was necessary because
we were using fireAt rather than fireAtCurrentTime. He also made a few
changes to the DEDirector to support the change request mechanism.
>From this, I changed our code so that the asynchronous fireAt() calls are
wrapped in a change request and the fireAtCurrentTime() ones are not. That
now works pretty well ... but I am occasionally seeing problems with
fireAtCurrentTime(). See the following stack trace:

it. Would wrapping it in a change request help? It seems a heavyweight
solution - I don't care when the DEDirector fires .. I just want to
trigger a firing at the next possible opportunity.
