           Summary: Leaks seen in MemoryPressureHandlerMac.mm on Leaks bot
           Product: WebKit

        OS/Version: Mac OS X 10.7
            Status: NEW
          Severity: Normal

http://build.webkit.org/LeaksViewer/?url=%2Fresults%2FLion%20Intel%20Leaks%2Fr100308%20%28129%29%2F shows that _cache_event_source and _timer_event_source in MemoryPressureHandlerMac.mm are being leaked.

It looks like MemoryPressureHandler::uninstall is canceling but not releasing _cache_event_source.

It looks like MemoryPressureHandler::holdOff will overwrite _timer_event_source without canceling or releasing it. (Perhaps uninstall should be doing this?)
