Solution committed upstream at revision 3586. Simple script I use to test this:
# yum install sesame
echo -n "`cat /etc/redhat-release` "
uname -m
rpm -q sesame
sesame --help 2>&1 | grep interval
And it's output:
---------------------------------------------------------------
Red Hat Enterprise Linux Server release 5.4 (Tikanga) i686
sesame-0.7.3826-3.el5
--pub-interval N (10) Publish interval in seconds
---------------------------------------------------------------
Red Hat Enterprise Linux Server release 5.4 (Tikanga) x86_64
sesame-0.7.3826-3.el5
--pub-interval N (10) Publish interval in seconds
---------------------------------------------------------------
Red Hat Enterprise Linux AS release 4 (Nahant Update 8) i686
sesame-0.4.3153-2.el4
---------------------------------------------------------------
Red Hat Enterprise Linux AS release 4 (Nahant Update 8) x86_64
sesame-0.4.3153-2.el4
---------------------------------------------------------------
So I will wait for RHEL4 packages and re-test then.
root@rhel4:~# sh sesame-test Red Hat Enterprise Linux AS release 4 (Nahant Update 8) i686 sesame-0.7.3826-5.el4 --pub-interval N (10) Publish interval in seconds [root@rhel4x ~]# sh sesame-test Red Hat Enterprise Linux AS release 4 (Nahant Update 8) x86_64 sesame-0.7.3826-5.el4 --pub-interval N (10) Publish interval in seconds

It's apparently at a rate of .2Hz, which won't scale well. We need a way to adjust/configure the rate.
