Hi.

We need improve our dumps, really.

First of all they are too big, because we dump whole memory.
Second of all, they are not safe for our users.

We should implement two things:

- dumping only kernel pages (dump is smaller and without sensitive data
  from userland processes);
- add a malloc(9) flag M_NOUMP which will prevent from dumping
  pages with sensitive data (e.g. GBDE keys).

Any VM-skilled volunteers? Pretty please...
