    Bug 24398: Plugin-container process exhausts memory
    
    The plugin-container process can thrash/crash due to increasing memory
    consumption after our workaround for bug 24052. The patch provided by a
    cypherpunk (bug thanks!) deals with that as far as the Developer Tools
    are concerned.
