Yes, at least that.

A "Solaris Zone" is apparently some kind of virtualization thing, with low CPU overhead.) s/multi-threading/multi-programming/ I suppose. I certainly hope you can still get performance while running many separate true processes in parallel. /Jorgen -- // Jorgen Grahn <grahn@ Oo o. . . \X/ snipabacken.se> O o . -- http://mail.python.org/mailman/listinfo/python-list
