--- Comment #24 from Paul Poulain <paul.poulain at biblibre.com> ---
I can't decide myself to push this patch. Let me share my comments:
 * it add a syspref to decide wether we should update this field through a cron
or in real time. The FAUSP (Fighters Against Useless SysPrefs) commitee has
some concern: if it's long to do, who will set this syspref to 1 ? Small
libraries have a low-grade hardware, large libraries circulate a lot. My
conclusion is that noone will set the syspref to 1. So the syspref could/should
be removed.
 * OTOH, the UpdateTotalIssues sub uses ModBiblio. It appears that it's because
the popularity sorting is based on 942$0 field. that's why it's so long & I
can't see another method to populate this field. 
 * In UNIMARC default setup, the totalissue field is attached to 942$0 like in
MARC21. Quite surprising according to me, but not wrong afaik
 * The install documentation should be updated to reflect the
misc/cronjobs/update_totalissues.pl (can be done later. Having crontab.example
updated is a good 1st step)

Please comment my point 1 (2, 3 and 4 are just here as a reminder, even if 4
will require a follow-up or another bugzilla entry)
