You are implementing a thread system, right?  You need to do
whatever is necessary to make the control "evaporate" and leave
behind an appropriate trail.

One common way to do that is to enter the thread runtime, remove the
thread from any ready lists it might be on, leave some breadcrumbs
in the thread control structure that it's gone, and do a context
switch.

Those are all user-level "how do I call it" guides, not details of
how to implement it.

Don't take this wrong:  Are you sure you're up to this?
