v0.7.0: pid files are not updated after SIGUSR2

[Patrick]

I've just installed the newest version and realized that our restarts do not work anymore.

We send SIGUSR2 to the pid defined in master.pid. That no longer works, because the pid files for master and the workers are NOT updated after after a SIGUSR2 to the master process.

seems fine to me, though I did notice the restart test case was broken due to the delay with the new mkdir stuff

It might have been a problem between screen and chair. I'll analyze it again and get back to you
