One warning - you currently need to make sure that the
WRITE_ADDITIONAL_DATA flag's presence or absence is consistent between
your write() and your read(), or the read will scream and die and give
you an utterly unhelpful error message.
In hindsight the amount of time it would have taken me to fix this
problem would have been less than the amount of time I've wasted being
bitten by this problem, however I'm not sure when/if I'll get time to
fix it now.
