// 34 * Creates two sets of two tasks. The tasks within a set share a variable, access
// 35 * to which is guarded by a semaphore.
// 36 *
// 37 * Each task starts by attempting to obtain the semaphore. On obtaining a
// 38 * semaphore a task checks to ensure that the guarded variable has an expected
// 39 * value. It then clears the variable to zero before counting it back up to the
// 40 * expected value in increments of 1. After each increment the variable is checked
// 41 * to ensure it contains the value to which it was just set. When the starting
// 42 * value is again reached the task releases the semaphore giving the other task in
// 43 * the set a chance to do exactly the same thing. The starting value is high
// 44 * enough to ensure that a tick is likely to occur during the incrementing loop.
// 45 *
// 46 * An error is flagged if at any time during the process a shared variable is
// 47 * found to have a value other than that expected. Such an occurrence would
// 48 * suggest an error in the mutual exclusion mechanism by which access to the
// 49 * variable is restricted.
// 50 *
// 51 * The first set of two tasks poll their semaphore. The second set use blocking
// 52 * calls.
