Review comment:
> The variable is also confusingly named since it is absolutely not the
'header size', its only non-header stuff than can ever get it into this
situation.
I can rework on naming to better capture what's happening here
> why not just send the generated first payload at this point (as the old
version did when the initial buffer wasnt big enough, in
retryInitialPacketWithExpandableBuffer())
I think it can be done, indeed, meaning that we will skip reading the file
at this round, let me rework to do it, I like it
