Think of this as an infinite number of named bathroom stalls. Each named stall can only be occupied by one person. When you TryLock(): a) it won't open if it's already occupied. (because it's locked inside) decide to do something else b) it opens and you get in and the stall gets reserved/locked for you. When you get out

you call the unlock callback you obtained from TryLock() to return the stall for use.

func (*M) TryLock Uses

func (n *M) TryLock(key string) (func(), bool)

returns false if gate already open/reserved returns true if gate was opened for you. you have to use the returned func to release it
