-/* fastrcv.c -- send many MIDI messages very fast. 
- *
- * This is a stress test created to explore reports of
- * pm_write() call blocking (forever) on Linux when
- * sending very dense MIDI sequences.
- *
- * Modified 8 Aug 2017 with -n to send expired timestamps
- * to test a theory about why Linux ALSA hangs in Audacity.
