relax shared segment access precautions
The shared array of peer type names is by design
append only, therefore no locking or copying strings
is needed to access it (only pointer conversions).
Append-only means that peer type names cannot be unregistered.
Unregistering is complicated because peers "cache"
the information they read from the shared array.

fix invalid shared pointer access and wrong retval
also, lock and copy string from shared segment,
as a precaution.

relax redundant shared access precautions
Shared access to the shared array of peer type names
was designed to be safe without locking or copying
because the peer type name array is append only,
i.e. no peer type names can be unregistered.
Unregistering introduces many other problems
(and not just the lock/copy avoided here),
such as need for "cache" invalidation among peers,
who had previously accessed the shared array.

fix invalid pointer access to shared segment.
Also, add locking and copying shared data, for safety.
