So maybe being able to specify a, b, c, d all complete within some
time from the process itself starting (i.e. a, b, c, d can all start
the process, but if (say) a starts it then b, c, d must arrive within
a certain time)...
expectActivities(a, b, c, d).
.expectWithin(seconds(1))
.errorIfOver(seconds(10)).to("activemq:overdue.b");
