Sorry I should have been more clear:
Basically, these compositions can be switched / toggled on and off at
random by a user.
Toggling off means renderAtTime is not called for say Renderer 1, but
instead by for Renderer 2.
So lets say Renderer 1 has been running for a while, and has a timer
to download some rss feeds occasionally
And I was curious if they 'keep downloading' even if when the renderer
associated with the composition does not have renderAtTime called in
the interim, seeing as how it is threaded (or.. not).
basically most of the time I do not get any stuttering/delays, but
occasionally I will get a large delay. I was curious if this was the
download patches getting funky. It was more of an academic question.
Thanks again,

As in, do they run if renderAtTime is never called? If you never
call it, they shouldn't ever execute. I don't think that's what you
meant though :)
Those are all threaded patches, so when you call renderAtTime, they
do a little dance, but the interesting parts are fired in a separate
thread that sometimes takes a bit to complete (at least, when
they're in async mode, which is the default). I'm not sure if QC
does thread-pooling, which may cause some strange stalls if there
are lots of outstanding stale requests, or if they're all their own
thread (which would then have fun lock stalls instead of pool
stalls). I think the Image Downloader does some caching now
(Tiger's didn't), but I'm not sure of its limits. Perhaps the
others do too? I've not played with them enough to know for sure :/
Maybe try setting synchronous mode in all of them, and then see what
happens?
