Stopping all javascript execution

Is there an equivalent to the php die() function for javascript that stops all javascript (including future callbacks for ajax requests, timeouts etc...) from running?

(NOTE: I can't use breakpoints in the debugger as the bug is in ie8 and the debugger prevents you from scrolling up/down the page while at a breakpoint; to be able to see at which point the bug is occurring I need to be able to scroll the page while the code is stopped)
