Severity: wishlist

Hi Carsten,
right now, pal wakes up every 0.1s when started with -m. This is bad for my
battery. Attached is a patch to only wake up every 25.5s. Please note that
keypresses still are going to be reported back to pal at once by ncurses, the
only drawback I'm aware of is that interrupt handling can be delayed as pal
records them but can only do its actions after the ncurses-timeout of 25.5s
happened, for example after an SIGWINCH (window-resize).
thanks,
youam
