Hello, I'd like to upload the attached changes to bullseye (already queued) [ Reason ] People have reported that when they work on the linux console with the espeakup screen reader, if they e.g. cat a long file, and the reader starts speaking it, and the user presses some key to interrupt the read, the screen reader remains silent for several seconds before it speaks anything again. That is because the speaking events for all the file reading have still been queued and the speak cancellation just makes them processed very quickly to flush the queue. Unfortunately there is a little usleep(50ms) that is performed on each event processing. This is a very old trick that was probably browntape-fixing some erroneous condition. We tried to remove that sleep and it didn't seem to have any nasty side effect. Upstream did commit the change and users are really happy with the change that completely fixes the delay. [ Impact ] Any action that creates long outputs (catting a long file, running dmesg, listing a long directory, etc.) introduce long latency even when the user wants to stop the speaking. [ Tests ] This was tested manually by the reporters. [ Risks ] The code by itself is trivial. The sleep was probably meant to "fix" something but it seems that that something doesn't exist any more. [ Checklist ] [X] *all* changes are documented in the d/changelog [X] I reviewed all changes and I approve them [X] attach debdiff against the package in (old)stable [X] the issue is verified as fixed in unstable [ Changes ] This just removes a spurious sleep.
