How do we determine if a node was modified during some transaction? I am 
asking because the entry I lookup from IC during unlock call (and before 
commit) always returns true for CacheEntry#isChanged, even if node was 
not accessed during tx.

If I lookup modifications through TxInvocationContext I do get correct 
modifications but here we are dealing with WriteCommands who do not have 
API to access key. So I have to check if WriteCommand is an instance of 
DataCommand....

My point is - there must be a better way to check for modifications that 
I cannot find in API :(
