+Be careful with this test, as the games might not always have /dev/dsp
+open (i.e. they may only use it periodically).
+
+Also, there could be problems with e.g. mmap where they might open the
+device and then fail to use mmap in which case they close it again.
+
+So try not to rely on this test only.
+
+Also if the open calls have been hijacked (i.e. soundwrapper has been
+used and is doing it's job correctly) it will likely not show up.
+
+So when testing make sure you do NOT use soundwrapper before doing your
+test.
