-------------------------------------

Here is the stack trace from a failed test run.

> {{TestPread#testHedgedReadLoopTooManyTimes}} fails intermittently.  It looks like a race
condition on counting the expected number of loop iterations.  I can repro the test failure
more consistently on Windows.
