Description

Keeps the thread in a busy waiting status.

Call SpinCycle to make the thread wait a number of CPU cycles before it tries to acquire the lock again. After 10 unsuccessful attempts, the thread sleeps for 1 millisecond every modulus 20 cycles, and sleeps for 0 milliseconds every modulus 5 cycles. All other cycles simply yield.
