xterm doesn't ;) Since I quit using konsole, my laptop is silent and cool.

ISTR a /dev/[pt]ty* pair is used for communicating with the shell.
/dev/ptmx is used to manage the [pt]ty pair. If I've understood it
correctly, konsole must write to ptmx on startup, but not every ten
seconds.

On this laptop: caldera 3.1. Custom 2.4.17.
