[Greasemonkey] Switching to Webpage Context

[Vincent Chute]

Nearly all of my user scripts are simply adding "behaviour" to specific 
"friendly" web pages.

Migrating from Greasemonkey 0.5.3 on Firefox 1.0.7 to 0.6.4 on 1.5 meant 
some of these stopped working.

5 of 9 worked without greasemonkey related changes (Firefox 1.5 changed what 
event.keyCode returns for key events), 2 were simple changes and 2 are 
proving more tricky.

What I would like to be able to choose to do is to execute the script 
outside the sandbox with the appropriate loss of privileges (I have yet to 
use any of the GM APIs).

I tried using unsafeWindow but I didn't manage to get it working 
successfully and whilst I could probably get 
document.createElement("script"); to work I don't fancy the pain of 
maintaining nearly 200 lines of sc.innerHTML += "...." especially with the 
effective loss syntax highlighting.

Are there any techniques that I am missing?
Anyone else interested in this ability?
