I will just unlink the tasklet from its current frame.
It is then useless, and the frame will be dropped.

Answers left to right: True, False, Maybe.
There will be preemptive switching.
At the moment, I have no way to analyse what is in
a stacklet. Simply dropping it might keep references
to objects, especially when the stacklet contains
data from some extension.
For that reason, I keep track of all tasklets. The user
has access, but I want to kill them by an exception,
when the program or this thread closes down.
