[opensource-dev] Script Memory Limits UI

[Lear Cale]

It used to be that simple, with original LSO.

With mono, it's more complicated, because two instances of the *exact*
same script can share the code segments.  I wonder whether this
sharing ability will be taken into account.  Ideally yes, because it's
best when the metrics used to measure something actually reflects the
thing you want to measure and optimize.
