This introduces a new "tiny" cache pool size (256KB) and ensures that, when
writeMsgRecordLockedis called for the first time on a new block, that we pull the underlying buffer from the pools. Subsequent calls towriteMsgRecordLockedwill reallocate from the pools manually instead of relying onappend()reallocating to a size that does not match any of the buffer pools.Signed-off-by: Neil Twigg neil@nats.io
