 // This file has been modified such that has_slots and signalx do not have to be
 // using the same threading requirements. E.g. it is possible to connect a
 // has_slots<single_threaded> and signal0<multi_threaded_local> or
 // has_slots<multi_threaded_local> and signal0<single_threaded>.
 // If has_slots is single threaded the user must ensure that it is not trying
 // to connect or disconnect to signalx concurrently or data race may occur.
 // If signalx is single threaded the user must ensure that disconnect, connect
 // or signal is not happening concurrently or data race may occur.
