* Memory ranges are represented with an RB tree. On insertion, the range

* so it can be searched within the range.

- * It is assumed that all setup of ranges takes place in single-threaded
- * mode before vCPUs have been started. As such, no locks are used on the
- * RB tree. If this is no longer the case, then a r/w lock could be used,
