---------------- * FreeExprContext * * Free an expression context, including calling any remaining * shutdown callbacks. * * Since we free the temporary context used for expression evaluation, * any previously computed pass-by-reference expression result will go away! * * If isCommit is false, we are being called in error cleanup, and should * not call callbacks but only release memor
