This is a long time annoying misconception i'm reporting here:

When a command is run from a shell and drives the kernel to use 100% of cpu
for a while, linux lets printing on screen anything that is typed.

[For techies: "But I can type text on the tty even if I run sleep 1000!"]

Oh yeah wow. It's been like that for what, 15+ years?
This is a shell feature - or bug, depending on how you look at it,
the kernel merely does what the shell did to the tty.
