Hi, Andy & Michael

About the problem that the telnet process consumes
CPU(bug1034218<https://bugs.launchpad.net/linaro-android/+bug/1034218>
),
For now I tried two ways to verify it:
1. Run the CTS test via submitting a lava-job
    In this way, the process that consumes CPU is telnet
2. Run the CTS test via command line "lava-android-test run cts"
    In this way, there is no process that consumes CPU to 100%,
    In the meanwhile, I also opened the telnet session.

So I guess the problem is the way we calling the telnet command in
lava-dispatcher.
>From my investigation, it's the select syscall in telnet that consumes CPU,
So I doubt if there is some place in lava-dispatcher that reads the ouput
of telnet in a loop without sleep in the loop.
but I did not find such place in lava-dispatcher.

How do you think about it?

Finally, I feel that this problem is of lava-dispatcher, not the problem of
lava-android-test or CTS,
so can we change it to be a bug of lava-dispatcher?
