Oops - you're right! I'll repost with that taken out. I must have
pushed the entire quilt series by mistake rather than just the patches
that are going upstream... so much for doing stuff late at night.
I haven't updated the FastMail patches website yet - the new patch
in there is the nested-transactions, which isn't heavily tested yet.
That said - the one I posted is stable as well, we're running it in
production with all those patches - but what I'm pushing for 2.3.13
is just those two patches you mentioned above. Here's a copy of
cyrusdb_skiplist.c with just those two.
