+/* ptlinux.c -- portable timer implementation for linux */
+
+
+/* IMPLEMENTATION NOTES (by Mark Nelson): 
+
+Unlike Windows, Linux has no system call to request a periodic callback,
+so if Pt_Start() receives a callback parameter, it must create a thread
+that wakes up periodically and calls the provided callback function.
+If running as superuser, use setpriority() to renice thread to -20.  
+One could also set the timer thread to a real-time priority (SCHED_FIFO
+and SCHED_RR), but this is dangerous for This is necessary because  
+if the callback hangs it'll never return. A more serious reason
+is that the current scheduler implementation busy-waits instead 
+of sleeping when realtime threads request a sleep of <=2ms (as a way 
+to get around the 10ms granularity), which means the thread would never 
+let anyone else on the CPU.
