* Memory ranges are represented with an RB tree. On insertion, the range
* is checked for overlaps. On lookup, the key has the same base and limit
* 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,
* with readers on the lookup and a writer if the tree needs to be changed
* (and per vCPU caches flushed)
