+    - API: there seem to be problems with the user of timer signals
+        in the BOINC API (Unix version).
+        On some platforms the signals are delivered to both
+        the worker and graphics thread,
+        and they can deadlock on something down in _vprintf().
+
+        Rather than try to sort this out,
+        we'll switch to using a separate thread instead of signals.
