1Smells like homework to me. What's the practical reason for this question? – Tom Cabanski Apr 28 '10 at 23:39

I don't take OS. My gf's having problems understanding the concepts as she's revising for her midterms. Honest to God that's the reason. – syker Apr 28 '10 at 23:41

You're on SO. So you can't possibly have an SO (Significant Other). LIAR!!!! – DVK Apr 29 '10 at 00:17

(If your GF doesn't already know this, she should be made aware that CS colleges are the most prolific users of plagarism detection software in the free world.)
Spinning lock:
To quote Lisa and Bart: "Are we there yet? Are we there yet? Are we there yet?" - cute in small quantities, extremely annoying in large doses.
Blocking:
The gate at the starting line of a horse track, or the locked door at a store before a product launch work as examples of blocking operations. You can't get your new iPad until some guy in a black t-shirt opens the door.
Condition:
Don't do anything (or keep doing what you're doing) until you hear otherwise from me.
