There is one restriction: all write accesses to a specific shared_ptr need
to be exclusive. This is the usual Posix model, also called "as thread safe
as an int" and "basic thread safety". It applies to most shared variables in
a program.

But I agree that it is easy to break the rules. And there is always the
possibility that your program is fine, but there might be a thread-related
error in shared_ptr (these are very difficult to find). So please let me
know if you find out more.
