would fail in spectacular ways on LOCKDEBUG kernels) by compiling the
groveler code twice (the second time with LOCKDEBUG defined so that
the appropriate structures get larger in the right way). We currently
decide if we are operating on a kernel with LOCKDEBUG enabled if the
kernel's vm_map has referential integrity between a few pointers
and/or values.
Also, if you use more than one -v, you get a * on a line by itself in
between gaps in entries. It makes finding gaps much easier visually.
