  1. Introduce (global) default config file locking 

    Adds LockDefault() and UnlockDefault() which lock an associate file
mapping to the same default containers file that Write() selects.
This functionality allows for multiple read-and-write operations
to be atomically executed by serializing access from multiple
updaters.

As an example, if two parallel updaters are inserting a different
entry into a map, one will likely be omitted from being
overwritten with data from a stale read. Instead, using these
functions, callers can coordinate, ensuring writes are never
interposed between another caller's read-update pattern.
