: The patch I've supplied has one bug in it that came up... While building
: the world one of my 'ranlib's got stuck in 'newbuf' even after plenty of
: buffers were freed up. I think it's a simple missing wakeup... when
: I spiked the load the ranlib got going again ( too bad, I was trying to
: gdb -k the running system and the gdb command unstuck the ranlib! ).
Fragmentation in the buffer_map, even though it is *twice* the size of
maxbufspace, can cause map allocations to fail due to fragmentation.
Joy.
