Dear All,

Interesting to note that this same point (about instantiating multiple
interpreters was raised on our mailing list...about 3-4 years back)....
by Yours Truly :))

See the mail chain titled: *"Ideas for Python concurrency..."*

Life is coming full circle :)

Take care,
Vishal Sapre



Thanks and best regards,
Vishal Sapre
