[REBOL] Re: Multi-threading?

Hi Matt,
<< Is it possible for REBOL to multi-thread? If that's what its called. Is
there an example on the rebol site? >>
REBOL scripts can't be multi-threaded, in the sense of pre-emptive
multi-threading like many modern OSs. Maarten Koopmans has written a
lightweight threading engine for use in Rugby, which does cooperative
multithreading, and I have built something similar myself.
Since multi-threading often causes more problems than it solves, the real
question is: Do you *need* it?
<< If a rebol script checked my inbox for messages and replied to those
that were on my "friends" list it would read and reply one at a time.
Is it possible to concurrently check multiple emails? >>
In this example, given that the volume will probably be very low, what does
it gain you? I.e. have you tried a regular version and found it to be
inadequate in some way?
Another approach, of course, is that you might build a larger system out of
multiple scripts, each of which would be handled by the OS but could
communicate with the others via some IPC mechanism.
