The GetMemberDetails subroutine is insanely inefficient, and is used throughout Koha's code. In many cases, GetMember is more than sufficient (please see my rant on bug 5179). This report shall serve as the meta-report for all attempts to eliminate unnecessary calls get GetMemberDetails. Please file separate bug reports for specific instances, and list them as "blocking" this report.
