*
* VSM stuff common to manager and child.
*
* We have three potential conflicts we need to lock against here:
*
* VSM-studying programs (varnishstat...) vs. everybody else
* The VSM studying programs only have read-only access to the VSM
* so everybody else must use memory barriers, stable storage and
* similar tricks to keep the VSM image in sync (long enough) for
* the studying programs.
*
* Manager process vs child process.
* Will only muck about in VSM when child process is not running
* Responsible for cleaning up any mess left behind by dying child.
*
* Child process threads
* Pthread locking necessary.
*
* XXX: not all of this is in place yet.
