 // This is a helper utility for base::Bind()ing callbacks on to particular
 // MessageLoops.  A typical use is when |a| (of class |A|) wants to hand a
 // callback such as base::Bind(&A::AMethod, a) to |b|, but needs to ensure that
 // when |b| executes the callback, it does so on a particular MessageLoop.
 //
 // Typical usage: request to be called back on the current thread:
 // other->StartAsyncProcessAndCallMeBack(
 //    media::BindToLoop(MessageLoopProxy::current(),
 //                      base::Bind(&MyClass::MyMethod, this)));
