Refinements to RetryingTransactionHelper to make it equivalent to

executeInUserTransaction().
Changed the on close callback for write listeners to use a RetryingTransaction.

to ignore transient resource contention failures.  CIFS, for example, will be able 
to take advantage of this, since a transient error condition currently results in a dead
share.
