I don't believe there is such a guarantee, unless the spec spells it out 
explicitly.

For async scripts, Gecko, does the initial script parse+compile on a 
random background thread from a threadpool, and if there is not an 
explicit dependency between the scripts (which I _think_ is only there 
for parser-inserted scripts) then the script will simply run whenever 
that script's background parse thread finishes.
