added spin lock with test
The micro-benchmark shows promise (run test manually with 'verbose' as
parameter). It indicates that taking and releasing the spin lock from
a single thread is cheaper than doing the same with a normal mutex (as
expected based on previous tests). However, it also indicates that it
is competitive with a normal mutex for short critical sections with
multiple threads involved. (on my laptop, only the cases using more
threads than cores run faster with a normal mutex, which is a better
result than expected).
