	I already have this flag and my code mostly work like this, so
that would be trivial to do.
	I looked at the code, and you are right, killing the tasklet
within itself is by far the safest way to do it. It's a shame that the
code doesn't explitely allow for it (i.e. you will deadlock every time
in tasklet_unlock_wait(t);).

	Thanks, and have fun...
