[sldev] Script/Parcel/Memory Limits - Memory Limit Configuration

[Darrius Gothly]

llEndScript(integer die=FALSE); ? Or maybe a parameter with constants: 
ENDSCRIPT_END, ENDSCRIPT_RETURN, ENDSCRIPT_DIE


The comment about "returning objects" comes from Babbage's office hours on 
the 9th of this month where he makes a comment about it.

      [3:42]  Babbage Linden:  that will include functionality for finding 
and returning scripted objects

      [3:42]  Babbage Linden:  so everyone will be able to find and clean up 
the scripts they don't need

      [3:43]  Babbage Linden:  before we start enforcing limits


However he does add just after that ...

      [3:44]  Babbage Linden:  no one else can see or return your 
attachments


And then goes the other way 10 minutes later ...

      [3:53]  Babbage Linden:  Jack is going to be communicating this to 
people

      [3:53]  Babbage Linden:  when the limits are enforced, you will end up 
with objects being returned

      [3:54]  Babbage Linden:  but hopefully everyone will have enough time 
to manage their attachments before that happens


So, yeah, I can understand why people are concerned.
