Comment 6

[Joel Maher ( :jmaher ) (UTC -8)]

this failed in confirm failure mode (run 4x in the same session). This indicates one of 2 things:

1. this failure is easier to reproduce/debug and could become more frequent
2. this test doesn't work well when run multiple times in a row (if so should be annotated with skip-if = ["verify"])
