It definitely is not orthogonal. Suppose an OS thread goes into an infinite loop. How do you cleanly stop it (feel free to assume Linux/Windows/MacOS)?. In Erlang this is possible because of the custom threading implementation.

In Erlang that's possible because the program runs in a VM. Erlang could do the same with 1:1 and m:1 threading.

It's because of the vm interpreter that calls into the scheduler within loop iterations. Nothing to do with threads.

The JVM manages this - there are many options:

- reading a flag - patching the running - changing memory protection and causing a segfault

ptrace it?
