Description

Can anything be done about this hang?

RtlpDeCommitFreeBlock (in wntdll.pdb)
 -> DWriteFactory::GetSharedFactory() (in DWrite.pdb)
 -> CreateFactory(DWRITE_FACTORY_TYPE,_GUID const &,IUnknown * *) (in DWrite.pdb)
 -> gfxWindowsPlatform::UpdateRenderMode() (in xul.pdb)
 -> gfxWindowsPlatform::gfxWindowsPlatform() (in xul.pdb)
 -> gfxPlatform::Init() (in xul.pdb)

Sometimes the top frame is EtwEventEnabled (in ntdll.pdb)

Maybe we could create the factory on another thread?
