I often find Safari blocking because of some plugin taking too much
time. The usual culrpit is
Quicktime. I decided to run Spin Control today and got a block of 158
seconds. I wouldn't be
surprised of many people would have opted for a 'force-quit' beyond
the 60 second mark. Anyhow
here is the output from 'Spin Control':
