Actually, the issue is that the meaning of the milliseconds argument is:
If the value of the argument is 0, then wait forever (until the other thread dies.) If it is not zero, wait until the other thread dies, or until the timeout value is reached, whichever comes first. The semantics of the argument are arbitrary in that 0 means "wait as long as it takes."


All code in my posts, unless a source is explicitly mentioned, is my own.
