[twitter-dev] Delete messages from the "filter" stream with location parameters??

[M. Edward (Ed) Borasky]

I'm doing some testing with the "filter" stream using location
bounding boxes around PDX. I can send a geocoded tweet, and it shows
up in the output of "filter" not too long after that. But when I
deleted the tweet from the web app, I never saw a "delete" message
come down the filter pipe. Should I see one? How long should I have to
wait for it?
