Limit recursion depth for $Flow$DebugPrint aggressively
Limit recursion depth for $Flow$DebugPrint aggressively

Summary:
```
declare var flowDebug: $Flow$DebugPrint;

declare var p: Promise<void>;

flowDebug(p);
```

Before, this example didn't terminate in a reasonable amount of time. I'm not sure exactly what's going on, but limiting recursion here a little more (the default is 1000) seems like a reasonable thing to do.
