           Summary: ThreadTimer: avoid blocking UI when too many timers
                    ready to fire
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Other
        OS/Version: Other
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: WebCore Misc.
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: yong.li at torchmobile.com

Current ThreadTimer fires all timers that meet the fire time. This can block
UI, if some of those timers are big time-consumers.

Solution is to set a timeout when firing those timers. When time is out, those
unfired timers should be postponed to next time.
