Implements a read-only Set wrapper.

Although this is advertised as immutable, it really isn't. Anyone with access to the wrapped set can still change the set.

Implements a thread-safe Set wrapper. The implementation is extremely conservative, serializing critical sections to prevent possible deadlocks, and locking on everything. The one exception is for enumeration, which is inherently not thread-safe. For this, you have to lock the SyncRoot object for the duration of the enumeration.
