Since D has the synchronized keyword in the language, implementing simple
mutexes and/or critical sections are straightforward and trivial.  However, I
have not found thus far any language (or phobos class) implementing something
like a condition variable.

Am I just missing it?  It's certainly possible, as I am just now being able to
dive down into D.  

CondVars (or, more easily, counting semaphores, which are useful in some
situations that condvars are) are of course implementable by anyone based on a
Mutex primitive, but it seems like they would be a good addition to the library.

There isn't one in Phobos.  Tango has a locks package in the works which 
contains semaphores, condvars, read/write locks, and a few other things 
though, IIRC.  If all goes as planned it should be in the next release.
