currently all loggers can always accept messages and never suggest flushing buffers. in the future this may change, and at that point we're already fully set up for it. local loggers should never keep asynchronous (i.e. network-backed) buffers, disk buffers are fine. networked loggers will require buffers and periodic flushes later.
