+## Purpose
+
+To avoid running expensive IO or computation concurrently.
+
+If the result of IO or computation is requested while an identical request
+is already in progress, wait until the first one completes and provide its
+result to every routine that requested it.
+
+## Usage
+
+Provide:
+
+1. a named key for the computation or resource,
+2. a callback to handle the result
+3. an implementation which calls back with the result
