+ * Notes on handling system time adjustments (especially negative ones).
+ * ---------------------------------------------------------------------
+ *
+ * This solution was suggested by Alexander Terekhov, but any errors
+ * in the implementation are mine - [Ross Johnson]
+ *
+ * 1) The problem: threads doing a timedwait on a CV may expect to timeout
+ *    at a specific absolute time according to a system timer. If the
+ *    system clock is adjusted backwards then those threads sleep longer than
+ *    expected. Also, pthreads-win32 converts absolute times to intervals in
+ *    order to make use of the underlying Win32, and so waiting threads may
+ *    awake before their proper abstimes.
+ *
+ * 2) We aren't able to distinquish between threads on timed or untimed waits,
+ *    so we wake them all at the time of the adjustment so that they can
+ *    re-evaluate their conditions and re-compute their timeouts.
+ *
+ * 3) We rely on correctly written applications for this to work. Specifically,
+ *    they must be able to deal properly with spurious wakeups. That is,
+ *    they must re-test their condition upon wakeup and wait again if
+ *    the condition is not satisfied.
