[PATCH] threadutil: add missing import os

[Nicolas Sebrecht]

We are missing this import since commit d839be3c61888a837b
(Sat Apr 16 20:33:35 2005 +0100) which was when John switched from SVN to Git.

Nobody seemed to raise a missing import which make me think this code is either
highly broken (we have dead code) or very safe. It would ask a closer review of
this area.
