Instead of spawning a separate process for each test, move the code to
run in the main process. This gives us correct coverage information and
makes the tests a lot faster.
The input is still provided in a kickstart file. The output also goes
into a log file that is later parsed.
There is some extra work needed with logging setup to make the logs go
to standard output so that nose can correctly capture them.
