    Executes function f under transaction protection.

    Executes function f under transaction protection. Following is the lifecycle of the Transaction here:

    1. Create Transaction 2. While creating valid transaction, also store the valid Transactions (validTxns) at that point. 3. Acquire Locks 4. validTxns could have changed at this point due to transactions getting committed between Step 2 and 3 above. Abort the transaction if it happened and Retry from step 1. 5. Execute f 6. End the transaction

    Note, if transaction was already existing for this thread, it will be respected.
