Are there any open collector issues for this?

I think the stuff we were talking about has been resolved, since there's 
only one use of os.platform now, and I'm pretty sure it needs to be there...

Indeed. I made things a lot better by turning the security policy back 
to the C implementation. I've also noticed that the real slowness only 
comes when I hit the reload button on IE or Mozilla, without any Ctrl or 
Alt modifiers. Why would this cause all the images to reload?

I feel like I'm missing something simple that I should sort out before I 
start profiling...
