A note from Steve with A more complete description of the problem:
Web Inspector appears to be displaying incorrect network timing info that's thrown off by JS execution in the page. Here's an example page:
http://stevesouders.com/cuzillion/?c0=bj2hfff1_5_f&c1=bi2hfff2_0_f
There are two resources. Both start downloading at about the same time. The script finishes downloading around 1 second. The image finishes downloading around 2 seconds. This is in fact the behavior shown by HttpWatch and Firebug Net Panel.
However, when viewed in Web Inspector in Chrome the image is shown as taking ~6 seconds to download. That's because the script has a 5 second tight loop. This is likely blocking the Web Inspector from determining the correct timing for the image download. (I verified the true image download time by watching my server logs.)
