You're welcome, thanks for your help with the test. I hope that it would
help you to implement FileIO in Python.

FYI I saw EINVAL errors on test_large_read() on some buildbots, Mac OS X
and FreeBSD if I remember correctly, when I forgot the bigmem decorator.
And FreeBSD kills the process if there is not enough memory.
