Keep your Web applications running when tasks lock up. High volume Web sites often require asynchronous or threaded operations to achieve target performance criteria. While threads in Web containers are considered bad practice, the alternative is for developers to make blocking calls to code they cannot control. It becomes important that dependencies of this nature fail-fast. This developerWorks article covers a homegrown short-circuit pattern that ensures threaded execution and completion of a process in a fixed window of time.

Urban legends are kind of like mind viruses; even though we know they are probably not true, we often can't resist the urge to retell them (and thus infect other gullible "hosts") because they make for such good storytelling. Most urban legends have some basis in fact, which only makes them harder to stamp out. Unfortunately, many pointers and tips about Java performance tuning are a lot like urban legends -- someone, somewhere, passes on a "tip" that has (or had) some basis in fact, but through its continued retelling, has lost what truth it once contained.
