It depends on what you mean with synchronous.  An implementation may
write the new resource to its internal db and then reply with 201.
But that doesn't mean that the new resource is "used" or "applied" at
that point in time, so in that sense it can be viewed as
asynchronous.  Some other implementation might not return 201 until
the resource is really applied.
