I think locking on public members is not unsafe. For example locking on
SyncRoot (where applicable) is good as it will sychronize the operation
accross all its wrapper methods.
And never forget that if someone wants to cause deadlock (or do other evil
things) he can do it using Reflection as well as anyone
(ReflectionPermission is rarely revoked) can read and even write private
