Yes. Each child record is read individually so that the deleteRecord() method can be called to deal with any grandchildren (and great-grandchildren, et cetera). If you have audit logging turned on then eah deleted record is also written to the log file.

If you want to turn logging off for deletes you can set $this->audit_logging to FALSE in the _cm_pre_deleteRecord() method an back to TRUE in the _cm_post_deleteRecord() method.

If you want to delete all children and ignore the possibilty of grandchildren you can insert code in the _cm_pre_deleteRecord() method to cycle through the array of child tables and perform a deleteSelection() on each one. This will then delete any child records on that table without having to read them first.
