...as the signal can potentially be delivered to the to-be-joined thread. (It is unclear to me whether the SalMainPipeExchangeSingal_impl handler is really needed anyway, as there are various other places that should ensure that DisableOfficeIPCThread is called during shutdown. At least in theory, no longer joining here can cause the thread to incur crashes etc. when it it still running during shutdown.) Change-Id: I677a2e31e1a58d2b8d91634c2eb5274d63ac15f4
