This routine claims to return the max number of holds a patron can place on a record, however, it does not take into account whether a patron can hold an itemtype or not, so may be inflating the maximum number when the patron cannot in fact hold those items

We really only need to call once per itemtype and branch combination - if reserves control branch is 'patrons library' then it is really only once per itemtype on the biblio
