/**
 * Test log warnings that happen before the test has started
 * "Couldn't get the user appdata directory. Crash events may not be produced."
 * in nsExceptionHandler.cpp (possibly bug 619104)
 *
 * Test log warnings that happen after the test has finished
 * "OOPDeinit() without successful OOPInit()" in nsExceptionHandler.cpp
 * (bug 619104)
 * "XPCOM objects created/destroyed from static ctor/dtor" in nsTraceRefcnt.cpp
 * (possibly bug 457479)
 *
 * Other warnings printed to the test logs
 * "site security information will not be persisted" in
 * nsSiteSecurityService.cpp and the error in nsSystemInfo.cpp preceding this
 * error are due to not having a profile when running some of the xpcshell
 * tests. Since most xpcshell tests also log these errors these tests don't
 * call do_get_profile unless necessary for the test.
 * The "This method is lossy. Use GetCanonicalPath !" warning on Windows in
 * nsLocalFileWin.cpp is from the call to GetNSSProfilePath in
 * nsNSSComponent.cpp due to it using GetNativeCanonicalPath.
 * "!mMainThread" in nsThreadManager.cpp are due to using timers and it might be
 * possible to fix some or all of these in the test itself.
 * "NS_FAILED(rv)" in nsThreadUtils.cpp are due to using timers and it might be
 * possible to fix some or all of these in the test itself.
