0001-touchpad-add-separate-shorter-timeout-for-doubletap.patch

I don't think we can actually reduce the first tap timeout by much. If you hit
a ~200ms delay on a "normal tap" (comment #9) then reducing it further risks
missing it altogether. 

Note that we don't actually control the double click, we only convert tap to
button clicks, everything else is handled in the client (GNOME has a
doubleclick time setting).

Here's a patch that reduces the second tap timeout, I think that's better to
rely on. That should then also reduce the total time so we're more likely to be
interpreted as a click in the default settings of the client.
