-// A class that assists with fast shutdown of threads. You can set
-// a flag that says the thread should quit, which it can then check
-// in a loop -- and if the thread sleeps (using the sleep_* functions
-// on the class), that sleep will immediately be aborted.
-//
-// All member functions on this class are thread-safe.
