type borrowingTestConstraints …

// TestBorrowing tests borrowing of concurrency between priority levels.
// It runs two scenarios, one where the borrowing hits the limit on
// lendable concurrency and one where the borrowing hits the limit on
// borrowing of concurrency.
// Both scenarios are the same except for the limits.
// The test defines two priority levels, identified as "flows" 0 and 1.
// Both priority levels have a nominal concurrency limit of 12.
// The test maintains 24 concurrent clients for priority level 0
// and 6 for level 1,
// using an exec func that simply sleeps for 250 ms, for
// 25 seconds.  The first 10 seconds of behavior are ignored, allowing
// the borrowing to start at any point during that time.  The test
// continues for another 15 seconds, and checks that the delivered
// concurrency is about 16 for flow 0 and 6 for flow 1.
