If threads are not quite make-able, then I think we would at least need
thread-safety. With the reduction in C code for the interpreter, I think
this might be more possible. Even if threads are not built-in, there are
still other libraries we can use for threads. So, what is certainly
necessary is thread-safety, which is the least of what's needed.

I know I can do that, but I was hopeing threads would be part of
Euphoria 2.5. It should run faster and be easyer to use. Priorities
could be very useful in more advanced programsy.
