/* utility: wait groups
*
* A Wait Group is a synchronization primitive that encapsulates a counter.
* A Wait Group is considered signaled when the counter is 0 and non-signaled
* when the counter is non-0. (Wait Group functionality is similar to Golang's
* sync.WaitGroup.)
*
* Wait Groups must always be allocated in non-paged storage.
