Mike - if you don't want to upgrade, but are willing to rebuild your
Cyrus package from source, you could just copy the attached
cyrusdb_skiplist.c file over the one in $BASEDIR/lib/ instead. I'm
pretty sure there are no cross dependencies.
This is taken from my 2.3.11 tree with extra patches (I seem to be
posting those patches a lot!) for sanity checking and integrity
assertions. With these patches applied I have been unable to cause
any damage to the underlying skiplist files no matter how hard I
abuse the API with my testing programs!
