Notes: all times are in microseconds (.000001) unless otherwise stated
Reading the hardware clock takes 3 `ticks' overhead
... this value will be factored out of all other measurements
Clock interrupt took 4.00 microseconds (264 raw clock ticks)
Testing parameters:
Clock samples: 32
Threads: 64
Thread switches: 128
Mutexes: 32
Mailboxes: 32
Semaphores: 32
