SimpleDelegator
This class provides a trivial way to synchronize all calls to a given object by wrapping it with a `Delegator` that performs `Monitor#enter/exit` calls around the delegated `send`. Example:
array = [] # not thread-safe on many impls array = SynchronizedDelegator.new([]) # thread-safe
A simple `Monitor` provides a very coarse-grained way to synchronize a given object, in that it will cause synchronization for methods that have no need for it, but this is a trivial way to get thread-safety where none may exist currently on some implementations.
This class is currently being considered for inclusion into stdlib, via bugs.ruby-lang.org/issues/8556
