1. A method of processing transactions within a computing environment, said method comprising: executing, by a processor, a transaction in the computing environment, the transaction effectively delaying committing transactional stores to main memory until completion of a selected transaction; determining, based on executing the transaction, that an abort condition has occurred; checking whether the transaction is a constrained transaction, the constrained transaction having one or more restrictions associated therewith; and returning to a beginning of the transaction to re-execute the transaction based on determining the abort condition and the checking indicating the transaction is a constrained transaction.
