Yes, setting reload to true makes Cocoon check file stamp, though with a
delay of xxx milliseconds if you specify a number (one of the other
parameters). Dynamically loading code might not work as expected, though
if you put the cocoon.load() *inside* a function, it might work
afterall.

Really dunno. Ask on cocoon-dev or try reading the code.. :-P

Not sure, but make sure to test thoroughly! :-)
