           Summary: REGRESSION: Timer bug causes gif animation and (html and
                    JS) page forwarding to fail
           Product: WebKit
           Version: 420+ (nightly)
          Platform: Macintosh
               URL: http://apple.com/developer
        OS/Version: Mac OS X 10.4
            Status: UNCONFIRMED
          Severity: major
          Priority: P1
         Component: New Bugs
        AssignedTo: webkit-unassigned at opendarwin.org
        ReportedBy: jshier at iastate.edu


On my quad, loading the test case for bug 5340 repeatedly will eventually stop
the gif animation. When it is frozen, it affects all gif animations, even in
other tabs. It also prevents html and JS powered forwarding, such as that
happens when trying to go to apple.com/developer. Testing with various people
in the IRC channel, and on my iBook 500, seems to indicate that this bug only
affects multiprocessor machines over a certain clock rate show this bug. A dual
1.42GHz G4 was reported to exhibit this bug, but a dual 500 and dual 867
didn't. For now I'm assuming this is a timer bug since that seems to be the
common element between the affected features, but I could be wrong. 

Essentially, reload the test case until it freezes, then no timers work at all,
even for already loaded content.

This affects nightly r12858.
