Introduce a short name for nicer print output.
Consistently increase tests to maximum of 12 threads.
Add #define DEBUG guards around verbose output.
Global statistics printing. Nicer dmesg format.
Print a column header to the console at the start.
Make sure individual stats are KERN_ALERT for console printing.
Make the master thread do the time keeping.

Additionally: it now becomes possible to report time keeping data in
the dmesg output because this is contained in the master stats
structure.
Add ability to set DEBUG ON to see debug output.
