also see #11301. I think the test case is over-strict. maybe we should remove the assertion for mount's epoch

Hmm, this is a bit weird. I don't know why mount_a is sometimes holding on to caps that get revoked when mount_b creates a file, and sometimes not. It all works quite dependably running the tests locally.

We could relax the test a bit, but the condition that mount_a's epoch doesn't advance is valuable, because it tells us that mount_b's epoch is advancing because of the barrier and not just in general.
