If this was done in C, as a series of patches to the current Nagios code
and not breaking compatibility with modules (being "config and output
compatible" is nowhere near enough I'm afraid), I'd be all over it.

As it's Python, which I neither speak nor read, I have no choice but to
say "Interesting concept, but I cannot approve of something I do not
fully understand".

Process pools aren't that hard to do in C really, but altering the
entire concept of how Nagios operates is a fairly big change. OTOH, I'm
not thrilled about the whole "check-results are stored in tempfiles"
thing either, and *that* was a major change too.

Jean, let's discuss how we can move this forward within the C-code
in such a way that we retain compatibility on all levels. Too many
have invested too much in Merlin, NDOUtils and other C-based addons
to relinquish them easily, and splitting the community again would
be really, really stupid.

Would it for example be possible to use Shinken as the checking
engine that supplies check-results back to a C-based scheduler
that retains config parsing and module compatibility? If that's
the case, we might be on to something. Otherwise, we'd better get
busy re-writing parts of the Nagios core to implement a process
pool.

Note that this would have to be a 4.0 release, so it won't happen
this year.

Considering the successes of the wars on alcohol, poverty, drugs and
terror, I think we should give some serious thought to declaring war
on peace.
