 ## potentially get the signal. In this case the `TResult` would still be empty.
 ## It shouldn't corrupt memory, but the `threadproxyds` TResult would return "empty".

+## Note I'm not sure if using ThreadSignalPtr's directly and closing them would work

+## that if both sides don't `close` the AsyncFD that are used, you'd just get events
+## from another pipe/socketpair which shares the same AsyncFD int's. Probably a solution
