Today it buffers N bytes worth of data in memory regardless of whether 
the tty is connected (or reading from).  How much it buffers is 
configurable via the store (by default the buffer has no limit so ensure 
console data is never lost).
Keeping a history wouldn't be a hard change.  I'll submit some patches.
