    What is this good for?

    lol wikipedia.

    I wonder if any phoronix readers can identify what the problems are with this statement (ignoring any and all grammar mistakes you may find or think you find):

    "Synchronization primitives such as mutexes, semaphores, and critical sections are all mechanisms by which a programmer can ensure that certain sections of code do not execute concurrently if doing so would corrupt shared memory structures."

    Here's a hint: If you're a computer science student, do NOT study for your exam by reading wikipedia.

    A critical section isn't a mechanism - it's the piece of code that will need to be synced inside a mutex, semaphore, or other solution.

    Well you're somewhat right, but it actually is a mechanism in windows:
