[opensource-dev] [server-beta] Script Memory Management Algorithm

[Lear Cale]

The intent isn't to try to exceed or even come close to hardware-based
virtual memory.  The intent is to isolate the effects of memory
overuse of one part of the system, to keep this from affecting other
parts.

However, I'd wager that you're right that it would involve a
noteworthy performance penalty, even when no paging is required.
