Doesn't that remove unmarked buffers only?

One potential hole are window configurations. Each window maintains two
lists for navigating the buffers previously shown in that window. For
live windows, these lists are hopefully updated when killing a buffer.
But if you store such a window in a window configuration and forget
about that configuration, the buffers from those lists are not reclaimed
IIUC.
BTW, I have no idea why FOR_EACH_BUFFER should be used outside alloc.c.
