Package singleflight provides a duplicate function call suppression
mechanism.
Group represents a class of work and forms a namespace in which
units of work can be executed with duplicate suppression.
Do executes and returns the results of the given function, making
sure that only one execution is in-flight for a given key at a
time. If a duplicate comes in, the duplicate caller waits for the
original to complete and receives the same results.
