    This type of synchronization object is known as a Gate.  The implementation is fairly well done, but you should change the if statements surrounding the Wait calls to while statements.  This guards against what's called "spurious wake ups".

    [Belated update:] wekempf and I exchanged a number of emails in February of 2009 discusing his recommendation to use "while" statements above. Summarizing briefly, his concern about "spurious wake-ups" is valid on other platforms (ex: UNIX), but is NOT valid for Microsoft's .NET implementation on the desktop or Silverlight. That said, alternate implementations of .NET by others for other platforms (ex: Mono) could introduce spurious wake-ups (though I think it would be in violation of the documentation (if not the specification) to do so). Therefore, using "while" would be safer, but is currently not known to be necessary on existing implementations.
