Currently, when a signal arrives in the main thread, the signal dispatcher is retrieved and called from the main thread, the dispatcher uses a proxy object that in turn sends an RPC to the entry point. This becomes a problem when the entry point destroys the dispatcher object, before the dispatch function has been called by the main thread. Therefore, the main thread should simply send an RPC to the entry point upon signal arrival and the dispatching should be handled solely by the entry point. Issue #1738
