New "default" buffer manager that aims to replace the current one, but

without deadlocks. Still need to track down a memory corruption bug
that this introduces, or exercises.

Added partial implementation of range tracking for pinning arbitrary
...
regions. Currently, tracks regions, and is O(m log(n)) for each
operation, where m is the number of transition points per range, and n
is the number of transition points in the system. A transition point is
a place in memory where the pincount changes.

The test sometimes calls append, append, truncate, where the first append terminates after the append, and returns EDOM. Check for this, and allow the test to pass.
