Comms tests failing (for me)

[osrf-migration]

Original report (archived issue) by Brian Gerkey (Bitbucket: Brian Gerkey, GitHub: gerkey).

I see the following tests fail on default:

[  FAILED  ] 4 tests, listed below:
[  FAILED  ] CommsTest.HalfMsgsDrop
[  FAILED  ] CommsTest.TemporaryOutage
[  FAILED  ] CommsTest.PermanentOutage
[  FAILED  ] CommsTest.OutagesAndDrops

The problem seems to be that expected message counts, which determined randomly, but which should be deterministic given a constant seed (which is set), don't agree. I get the following values reliably:

/home/gerkey/code/swarm/swarm/test/integration/comms_plugin.cc:173: Failure
Value of: expectedNumMsgs
  Actual: 347
Expected: this->numMsgsRecv
Which is: 354
[Dbg] [ServerFixture.cc:118] ServerFixture::Unload
[  FAILED  ] CommsTest.HalfMsgsDrop (1859 ms)

/home/gerkey/code/swarm/swarm/test/integration/comms_plugin.cc:173: Failure
