PS3, Line 111: cloudRead
This is also a cloud read

That's not a cloud read. Cloud read could be in readAndPersistPage but not 
necessary. See my comment in DefaultCloudReadContext

Not your fault, buy those checks are super ugly! See my comment in BufferCache.
We should have a no-op threadStats, where cloudPagePersist() and friends should 
do nothing

Move this to doStreamRead

PS3, Line 570: get
Create a new class NoOpThreadStats. This should be a singleton class. The 
constructor is private and NoOpThreadStats should have a single instance as

public static final IThreadStats INSTANCE = new NoOpThreadStats();

Use getOrDefault(Thread.currentThread(), NoOpThreadStats.INSTANCE);
