jQuery 1.2.1 is throwing a lot of warnings in firefox when javascript.options.strict = true

This causes a considerable slow-down when users have the setting turned on, firebug installed and set it to show javascript warnings

( http://dean.edwards.name/weblog/2007/08/firebug-slow/ )

fortunately for us, the number of warnings that get thrown when jquery loads is under 10, however if some measure is not put into place (eg, making all core developers test with the setting turned on and pay attention to the warnings) jquery will eventually run into the same problems dean ran into with base2.

(The following warning messages are copied directly from the console)
