Notes: all times are in microseconds (.000001) unless otherwise stated
Reading the hardware clock takes 73 'ticks' overhead
... this value will be factored out of all other measurements
Clock interrupt took 12.11 microseconds (399 raw clock ticks)
Testing parameters:
Clock samples: 32
Threads: 64
Thread switches: 128
Mutexes: 32
Mailboxes: 32
