// Chromium's SingleThreadTaskRunner interface. Currently only the bare minimum
// that is used by P2P part of libjingle is implemented. There are two ways to
// create this object:
//
// - Call EnsureForCurrentMessageLoop(). This approach works only on threads
//   that have MessageLoop In this case ThreadWrapper deletes itself
//   automatically when MessageLoop is destroyed.
// - Using ThreadWrapper() constructor. In this case the creating code
//   must pass a valid task runner for the current thread and also delete the
//   wrapper later.
