Any way to break/suspend a function?

[Tuxedo]

Hi!
I wonder if there's a way(or maybe it will be in (near)future) to break a function...
for example something like a check form the function LoadPic() while loading a BIG picture, so maybe will be possible to break or suspend(depends on circumnstances) and than continue without restart from the beginnig...
That maybe usefull also on personal functions that maybe launched meantime you do something else...
Somethinglike a generic Asyncronous object, not only for anim/music...
Sorry for stupid quesion

That's not possible because it would lead to severe concurrency effects. Hollywood is not designed to handle this.

I know that...
However when functions locks the entire progrsm sometimes was really problematic for me...
I hate to lost the control of the program...
