Error while developing gotop

gistfile1.txt

Some thoughts about this. I ran the coverprofile on this test and found that process.go never reached the case <- done: where the function is supposed to return, and close its channels in the cleanup function. I don't know if process_test.go closed the channel correctly. I will return to this when I deal with the process memory issue.
