in RKWard we run the following periodically during idle phases:

// this basically copied from R's unix/sys-std.c (Rstd_ReadConsole)
#ifndef Q_WS_WIN
	for (;;) {
		fd_set *what;
		what = R_checkActivityEx(R_wait_usec > 0 ? R_wait_usec : 50, 1, 
		R_runHandlers(R_InputHandlers, what);
		if (what == NULL) break;
	/* This seems to be needed to make Rcmdr react to events. Has this always 
been the case? It was commented out for a long time, without anybody noticing. 
	R_PolledEvents ();
