(Smacks self on forehead.)  Yeah, here's an (untested, quick and dirty) 
implementation of parallelCount().

size_t parallelCount(alias pred, R)(R range) {
     // Use the fact that bools are implicitly convertible to ints.
     return taskPool.reduce!"a + b"( cast(size_t) 0,
         std.algorithm.map!pred(range)
     );
}
