(This is probably actually a caching bug, but couldn't find where to file such bugs against. Feel free to reassign to a better component.)
I've seen this bug every once in a while ever since the 1.17 deploy, but was never able to reproduce it for debugging. I happened to catch it by accident with Firebug running today. It looks like what happened is:
1. The browser requested the page itself, which loaded in half a second
2. The browser next requested
which waited for 6.2 seconds and then returned 0 bytes (but status 200 OK). The Cache headers on the response from bits were:

Data Size 0
Fetch Count 28
Of course reloading the page fixed the problem, as it always does.
We've had an out-of-sync server in the pool for a while, that may have been what was causing this.

Appears to be fixed in general.
If still happening make sure it's not bug bug 28840 or bug 28857. Otherwise re-open this bug.
