Angular-cli: High CPU usage during "ng test" idle

[bobrosoft]

Please provide us with the following information:

1. OS?
   MacBook Air on Mac OSX El Capitan 10.11.1
   Also tested on MacBook Pro with Mac OSX El Capitan 10.11.4
2. Versions.
   angular-cli: 1.0.0-beta.10 (also tested on 1.0.0-beta.6)
   node: 4.3.1
   os: darwin x64
3. Repro steps.
   ng new testproj
cd testproj
ng test
4. The log given by the failure.
   All compiles normally, no issues, tests passes.
   But after that angular-cli process starts to consume from 80% to 200% of CPU (depends on project complexity, on empty project it's 80%)
5. Mention any other details that might be useful.
   High CPU usage slows down all things, compilation and dev process.
   In the same time if you run ng serve, it not consume CPU while idle.
   Tried with watchman installed as well -- same issue.

FYI, there are people working on redoing the build system so this could change significantly in the near future.

@aciccarello yes, but nobody reported that before and that's kinda critical one, want to rise a flag.
