+// what to do within waits: in wxBase we don't do anything as we don't have
+// the event loop anyhow (for now). In GUI apps we have 2 cases: from the main
+// thread itself we have to call wxYield() to let the events (including the
+// 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
+// the events will be processed by the main thread anyhow, without calling
+// wxYield(), but we don't want to eat the CPU time uselessly while sitting
+// in the loop waiting for the data
