Subject: [PATCH] Fix NetBSD thread scheduling problem.

Defining thread priority for SCHED_OTHER is implementation defined.
Some platforms like NetBSD cannot reassign it as they are dynamic.

<http://pubs.opengroup.org/onlinepubs/9699919799/functions/pthread_getschedparam.html>

Credit goes to <kamil@netbsd.org> and <riastradh@netbsd.org> for finding this
solution.
