While testing TabUnloader, I saw DefaultTabUnloaderMethods.iterateProcesses failed because tab.linkedBrowser was null or a browser context's currentWindowGlobal was null.

Set release status flags based on info from the regressing bug 1682442

TabUnloader is disabled by default. To hit this bug, a user needs to enable this feature through the pref and to have a low-memory situation with more than 10 inactive tabs. Even if they hit the issue, a symptom is that tabs are not unloaded. Setting the status to wontfix.
