I now have a wild thread going which I wish to kill.  Hitting "Stop" in Drscheme seems to only kill the formost process.  Obviously I could close out drscheme, and restart it, but I plan to be accidently creating many more wild threads throughout my development process.  Ideally I'd like to be able to just terminate the wild thread without stopping any of the others. I was thinking of writing a "thread manager".  I.E. something like the popup window for operating systems that let you kill processes.  Basically a list of all running threads, and a "kill by mouseclick" callback, or something.  So my questions are: #1 has something like this already been written? #2 Does there exist a "get-list-of-all-current-threads" call?  If not, I'll have to register my threads myself, and my solution will end up being specifc to my application, and won't be usefull to anyone else.
