//     and then cancels the context of request 2.
//  6. The exec fn of request 1, if StartRequest 2 returns a req2 (which is the normal case),
//     calls `req2.Finish`, which is expected to return after the context cancel.
//  7. The queueset interface allows StartRequest 2 to return `nil` in this situation,
//     if the scheduler gets the cancel done before StartRequest finishes;

// automatically even if the server doesn't cancel is explicitly.
// This is required to ensure we won't be leaking goroutines that wait for context
// cancelling (e.g. in queueset::StartRequest method).
// Even though in production we are not using httptest.Server, this logic is shared
// across these two.
