It shouldn't. The whole point of posting it is so that other are able
to test and review it. That is why I always mention the overflows.
Right now it's stable enough for production for me, haven't seen any
overflow since adjusting the growth rate, but it would be nice if
somebody with a different vdr setup tested it too (eg a FF card based
It will take weeks to verify that the code works as expected (the goal
is to have _fewer_ overflows (compared to the static buffers) while at
the same time a much smaller working set).
