This class wraps the pidfile_* API from libutil. The destructor calls pidfile_remove() when an object is destroyed. This class is similar to std::unique_ptr<> in that it retains exclusive ownership of the pidfh object. In addition to release and reset methods, write, close, and fileno methods are provided as wrappers for pidfile_*.
