That wasn't clear originally, but I think you're right.

Perhaps, but even after killing the grab-flash process the /tmp/Flash*
file still hangs around for a while, so something else is going on. Some
more experimentation is needed.

[... time passes ...]

OK, I took another look and it seems we are talking at cross purposes
here. On my system, using both Firefox and Chromium, the Flash plugin
does *not* delete the buffer file when it has finished playing. The file
only disappears when another file is opened or the browser terminates.

This is on F13 using the 64-bit flash plugin in
libflashplayer-10.0.d20.7.linux-x86_64.so.tar.gz (from Adobe).

If this is a different setup from what you have, I apologize for wasting
everyone's time.
