Wait a minute. Under Javascript, The behavior induced by this pattern is EXACTLY equivalent to that of CACHING the result directly and a BLOCKING call. The pattern is completely pointless if you view it from that angle. Might as well use blocking calls and a regular cache rather then async calls and cached promises. So then the benefit of this pattern is essentially it's a way for you to turn your async functions into cached non-async functions. Is this general intuition correct? --edit: It's not correct. Different async functions will still be in parallel. It's only all blocking and serial under the multiple calls to the SAME function.
