I didn't know about guard-pages feature.

Our kernel also has the concept of guard-pages, meaning it will try to
keep a gap of 1 page between mmap() allocations.
The way it is coded, it isn't perfect, but it tends to work and
catch some issues.
I am investigating what problems can bt detected with MALLOC_OPTIONS.
SEGV occurs even if MALLOC_OPTIONS=G is not specified. Normally, the
areas allocated by malloc() are not contiguous. However, after many
malloc() operations and not free() these areas, contiguous areas may
be allocated. I gues
Like with route messages we should really only forward pfkey messages
that made it past the validation step. This fixes a lot of possible
crashes in ipsecctl -m.
ok?

It's always the same:
* foobar doesn't behave as expected
* I ktrace foobar
* I run kdump... too much information.
* I check the kdump(1) man page, since I can't remember which letter
represents which tracepoint.

Sigh. Yes, dupl
