[PATCH 1/2] unbound: Only launch one process

[Michael Tremer <michael.tremer@ipfire.org>]

[-- Attachment #1: Type: text/plain, Size: 1588 bytes --]

When unbound is running multiple threads, we have observed
that queries where sent for each thread.

Since no user should have so much DNS traffic that more than
one processor core is being saturated, this is a safe change.
