Ajax, Browsers, Running Out of Time:Help is on the way, in the form of bytecode interpreters and vm’s for Safari and Mozilla, though the future of IE is still cloudy (still, there is a plan to bring Tamarin to IE). But if the new Browser version don’t arrive quickly enough, or if they don’t fully solve the problem of browsers crashing once an hour, then a mass migration to Opera may be the best we can hope for. At worst, content and application producers will opt for more stable non-Ajax alternatives such as Flash or Silverlight.
[I’m no so heavy a user of my browser under most conditions. I find apps that connect to the web either as services or as app specific browsers are a more compelling experience, and so many of the “web apps” I use run locally on my desktop while I have my home environment. But I can see the problem and work hard as coder to minimize the problem, would be nice if the lower level stuff made this easier and less leak prone.]
