+// GUI events and the low-level (not wxWindows) events from GSocket) be
+// processed. From another thread it is enough to just call wxThread::Yield()
+// which will give away the rest of our time slice: the explanation is that

+// wxYield(), but we don't want to eat the CPU time uselessly while sitting
