Yes, except with fewer confusing names :-)
The name used now (there was a rename patch following this) is
`ThreadsafeFS::view` - it took us a couple of years to work out what this
abstraction really was.
The purpose of using the same name for the two public overloads is that they do
the same thing. The purpose of using the same name for the public no-CWD
version and the version to be overridden is that they *are* the same thing.
These are more important reasons than the idea that non-existent
non-polymorphic callers will miss an overload.
("More important" subjectively, but code always ends up stamped with the taste
of the people working on it...)
