> This test does the following:
> - creates four channels a,b,c,d
> - injects views A: {A,C,B}, B:{A,C,B}, C:{A,C,B} and D: {B,A,C,D}
> - injects a merge event in each of channels A,B,C,D representing these four views
> - checks that all channels have the final view of size 4
> The test fails intermittently on RHEL, with the same failure each time:
