+ * OracleAdaptorChannel.m (+initialize): set the prefetch memory
+ size from a new "OracleAdaptorPrefetchMemorySize" userdefault. Use
+ "16 * 1024" by default.
+ (-evaluateExpression:): make use of the new prefetchMemorySize
+ variable to configure the OCI_ATTR_PREFETCH_MEMORY on the
+ statement. We also set OCI_ATTR_PREFETCH_ROWS to an unreasonably
+ high number to ensure the memory size always has precedence.
