True, if serialization isn't a problem, setjump/longjump may be a workable
solution.  However, if you want to implement something like what is called a
'latent function' in unrealscript for use in your AI the serialization
issues need to be contended with.  This will come up even if you don't use
lua for your save games.  If you don't need this functionality you'll be in
the clear.  Unfortunately for me, I do want this functionality as it will
simplify level scripting greatly.

Allowing level scripters to write stuff like:

dosomething()
waitforevent( "some game event" )
donextthing()

would be a big win as far as script complexity goes.
