One more to seal the deal to improve unloading inactive chunks

Browse Source 
While last was mostly there, still had some slight risk of unloading
before it was fully finished.

So just going to bump the delay to 3 minutes to be safe. Better than
forever at least.

Was really hoping we could unload them as soon as they were done to
any memory prematurely promoting to old generation, but guess we can't.
