The implementation is quite ok.
```test
"memory safe" in {
val count = new AtomicInteger(0)
Source(1 to 1000000)
.mapAsync(parallelism = 100) { _ =>
Future {
count.incrementAndGet()
new Array[Byte](100 * 1024)
}(system.dispatcher)
}
.map(x => {
println(s"More ${count.decrementAndGet()} elements need to be
processed")
if (count.get() > 100) {
throw new IllegalStateException("OOM likely occurred, too many
elements in flight")
}
x
})
.runWith(Sink.ignore)
.onComplete(_ => println("Completed without OOM"))(system.dispatcher)
}
```
You can see, it will never exceed 100
