In sequence diagrams messages are shown as synchronous/asynchronous
using a half-stick arrowhead, which can be supplemented with extensions such
as balking, time-out, guarded etc.

The focus of control is also present to indicate the active nature of the
object(s)
so it is quite simple to represent tasks/concurrency.
