Yes.  netclasses does this with its asynchronous connections.  Look at
these methods in GNUstep source:

-[NSRunLoop addEvent: type: watcher: forMode:]
-[NSRunLoop removeEvent: type: forMode: all:]

and implement the message:

- (void)receivedEvent: type: extra: forMode:



for how netclasses uses this to add its connections.
