It needs more work AFAICT because with it, espfix area gets cut off
prematurely:

and I think we want to see something more from the espfix area (this is
what we have now):

But yeah, this issue needs to be addressed one way or the other as the
espfix dump skips the runtime services.
And frankly, I don't see where we're setting that ->max_lines thing but
it sounds like a promising thing to use. :)
Thanks.
