Its failing to read bytes from /dev/urandom if a cursory inspection of the
source is accurate.  Thats really weird, since /dev/urandom doesn't block
and will always return the number of bytes requested (unlike /dev/random
which may return less than requested).  So, I'm not sure whats going on
here.  A good next step, if you're willing to help out, would be to
construct a test programme that just calls nextBytes() over and over again
and see if you can reproduce the problem with that.
