The task notifies the handler that it has started some new activity
(possibly a sub-activity of another activity already making progress;
therefore, these notifications behave in a stack-like manner).

Parameter Status
An object representing the new activity. There has to
be an agreement between caller and callee of methods
XProgressHandler::push and
XProgressHandler::update as to which Status
arguments are meaningful. For example, a string argument
to XProgressHandler::push should be used to transport
some status text that describes the progress being made (possibly
followed by one or more XProgressHandler::updates with
string arguments, if the appropriate status text changes
as progress is being made).
