Yes, that's exactly what I'm observing here.

Again, same observation here.

It definitely happens in text mode console too.

Just one more hint: After typing something on the console, it takes
2 to 5 seconds BEFORE there is disk activity, then there's a reply.
It seems like SCHED_4BSD (?) needs some time of its own before
deciding to swap the process back in (just guessing here).

However, this doesn't explain why the mouse freezes in X while in
motion. Perhaps when moving over a window of a long time idle process?
