As I replied in another message, there _is_ in fact one registry key
(which you can think of as a directory) per user, group, and alias.

And the locking of the registry file is done by the _kernel_ by virtue
of the fact that it's been loaded into the registry hierarchy.  _Any_
process can access the data within it (via the registry apis) provided
they have the proper permissions.
