Comment 4 for bug 1556175

Further bisection shows that 4.3.3-5ubuntu5 is the last version that works, and 4.3.3-5ubuntu7 is the first version that fails (ubuntu6 cannot be tested as that FTBFSed).

The corresponding diff is http://launchpadlibrarian.net/242313487/isc-dhcp_4.3.3-5ubuntu5_4.3.3-5ubuntu7.diff.gz -- the change was that this now links to the non-export bind libraries. There is no rationale/explanation of that, but supposedly the internal libraries handle SIGTERM differently.
