Sometimes project keeps reloading on Meteor 1.6-beta.15

[SimonSimCity]

I sadly can't say that much about this problem, but maybe someone who also had this can step in:

I've updated Meteor to 1.6-beta.15 in the hope I could escape from #8648. It also works quite well ... just once a day (maybe after the 50th reload for testing) I suddenly see that the project keeps rebuilding itself and doesn't finish until I again change a file.

Here's exactly what I do and see:

1. I start the test environment of meteor (meteor test --settings settings-test.json --driver-package practicalmeteor:mocha --port 3100 --verbose)
2. After the app is initialized, I open http://localhost:3100/ in my browser, which reloads every time I change the code and the app is rebuilt.
3. After a couple of changes (have now worked 3h without any problem) - maybe 50 changes - I change a file and see that the site for running the tests loads abnormally long.
4. Watching the console I just see Local package version is up-to-date: '[...] running over the screen. In order to get more output (since the meteor-tool often overwrites it's last line on the console) I hold down the ENTER key to get a better overview over what happens.

Here I see the following (after removing duplicated and empty lines):

     Downloading missing packages              \
  Local package version is up-to-date: xolvio:backdoor@0.2.1
  Local package version is up-to-date: xolvio:cleaner@0.3.1
     Building the application                  /
     Building for web.browser                  -
     Building the application                  /
     Building for os.osx.x86_64                -
     Building the application                  \
     Reading project metadata                  -
     Scanning local packages                   \
     Preparing project                         \
  Local package version is up-to-date: accounts-base@1.4.0-beta.15
  Local package version is up-to-date: accounts-password@1.5.0-beta.15
     Downloading missing packages              \

To me it now seems that something either in os.osx.x86_64 or Building the application fails, because if I stop meteor and start it into test-mode I get the following order:

$ meteor test --settings settings-test.json --driver-package practicalmeteor:mocha --port 3100 --verbose
     Selecting package versions                /
  [[[[[ Tests ]]]]]                             
  => Started proxy.                             
  Local package version is up-to-date: accounts-base@1.4.0-beta.15

     Downloading missing packages              -

     Starting your app                         \
  => Started MongoDB.                           
     Starting your app                         |

Anyone having an idea of how to go on debugging? I'm quite assured this error will come again in a few hours.

An interesting fact though:

If I now change a file (and thereby cause a new project-build), the current attempt is aborted and the next one will get through.

Sounds related to #8942, but the fix for this was already in Meteor 1.6-beta.15 ...
