-------------------------------------------------+-------------------------
 There is a bug in boost 1.56 random_device implementation where it can
 fail to read from /dev/random with an exception

     "boost::random_device: EOF while reading random-number pseudo-device
 /dev/random: Success"

 The boost random_device code attempts to read 4 bytes from /dev/random,
 gets fewer but >0 bytes because /dev/random temporarily runs out of random
 data, and boost random_device incorrectly concludes that end of file has
 been reached and throws an exception, where it should just try to read
 more bytes.
