Just run ANY application that has an insertion point on a Portable and
watch the insertion point flashing. After 16 seconds it goes very
slow. This is part of the Portable's power-saving behaviour. What is
happening is that every memory cycle is getting 64 wait-states added
to it. Even when running off mains power.

There's supposed to be a system call that application can use to
convince the OS that it is still alive - presumably HC 2.0 doesn't
do this.
