The above error occurs intermittantly when testing on Strawberry Perl
5.12.2.0 32-but installed on Windows 7 64-bit.
The number of read octets varies from 70k at the lowest to just short of
the required amount. Presumably it gets all of them some of the time, as
the tests do pass periodically.
The failure rate is somewhere in the vicinity of 50% (I saw 4 failures
from 8 test suite runs).
