patches since 2.3.12-p2?

[Per olof Ljungmark]

Hi all,

Could some kind soul recommend what patches it makes sense to apply 
since the latest release? There are a number of them circulating on the 
list but I cannot figure out for sure which ones are generally safe and 
recommended.

In particular, anything that addresses
DBERROR db4: 176 lockers
(We don't use Berkeley at all. Switched statuscache.db from 
berkeley-nosync to skiplist to see if that made it go away but it did not.)

and
skiplist: unlock while not locked

Sorry if I'm asking the obvious...
