Lowering high CPU rates?

[Chipp Walters]

Stay away from using Idle,Idle rates, etc..They're there for legacy purposes.

The best way I've found to create a multi-task is by using 'send in
time'. It works well and reliably, and gives your users a chance to do
other things while waiting.

I've an image browser which creates thumbnails from a folder full of
images. It has both synchronous and asynchronous modes. While the
async mode is slower, it does allow the user to scroll through the
thumbnails as they're being generated.
