bitkeeper revision 1.1676 (42a306a07UKpLq27_iCaJyxJBbKedg)
More console cleanups. The console ring now overwrites its tail when
it fills, rather than stop recording output. The guest serial output
is only allowed to half-fill the serial output buffer, and now
respects hypercall preemption requests.
