Re: Routebricks setup

Hi Ahmed,

There was a thread scheduling bug in click1.7.0rc1.
It was later fixed here:
http://www.read.cs.ucla.edu/gitweb?p=click;a=commit;h=df94d46a16af8a061d1069d2c442f1132063bb87

So you can take the patch from commit
df94d46a16af8a061d1069d2c442f1132063bb87, apply the patch and
scheduling should work fine.
