Control flow methods

There are some helper methods which might be useful when writing code using ox’s concurrency operators:

• forever { ... } repeatedly evaluates the given code block forever

• repeatWhile { ... } repeatedly evaluates the given code block, as long as it returns true

• repeatUntil { ... } repeatedly evaluates the given code block, until it returns true

• never blocks the current thread indefinitely, until it is interrupted

• checkInterrupt() checks if the current thread is interrupted, and if so, throws an InterruptedException. Useful in compute-intensive code, which wants to cooperate in the cancellation protocol

All of these are inline methods, imposing no runtime overhead.
