Re: question on forcibly stopping a thread

[David Morris-Oliveros <david@...>]

The way that I'm terminating the thread is by preempting them out, and 
then removing the reference to them from the global lua table.

I am in charge of multitasking all my coroutines, and i have a class 
that encapsulates the coroutine, so i keep a variable with the "state" 
of the thread at any given time, NOT_LOADED, STARTING, RUNNING, 
SLEEPING, DEAD, KILLED.

So if it's DEAD (because it's finished running), i just clean it up. But 
I can force the clean up by setting it to KILLED, then removing the 
references to it from the main globals.

Hope this helps, and hope that I'm not doing anything stupid.
