Mmm, what do you mean?  Could you explain the exact steps?

I guess you meant tty0.

Gasp! I though SAK would only kill it if it is used as session tty.

The problem is that we need to open /dev/tty0 for various stuff like
emulating key presses, knowing the current VT, etc.  We could close it
when not needed, but we still have to open it from times to times for at
least knowing which VT is active.  Pressing SAK would then sometimes
kill it anyway.

A solution would be to have a way to temporarily suspend the Linux
screen driver, then press SAK, then resume the Linux screen driver.
