The code in the tasks within this class are old and there are much better
ways to do these things now such as through tinfoil rather than writing csv
files incrementally with start/stop events and lock files.
Existing users of the code (mainly the do_checkpkg task) have been ported
over to tinfoil. Drop the class, any other users should also make use
of the tinfoil functionality.
