There are several places in the cluster module where a version of process.send() is called, but the result is swallowed. Most of these cases are internal, but Worker.prototype.send(), which is publicly documented, also suffers from this problem. This commit exposes the return value to facilitate better error handling, and bring Worker.prototype.send() into compliance with the documentation.
