--- Comment #1 from Jeremy Harris <jgh146exb@???> ---
Apart from signal-handlers, exim is not threaded so
"any other allocation between the allocation and extension of this buffer"
cannot happen (assuming we don't do allocations in sig-handlers).

There is presumably a bug, but I'm doubting the allegation of a race.
