Don't be misled by the patch description. The bug in Patch #1 can be 
reproduced in OpenLDAP with only a handful of transactions. I know, 
since I found the bug and reported it to SleepyCat in the first place. 
Anyone running BDB 4.2.52 without Patch #1 is going to have problems.

I don't believe OpenLDAP exercises the code path that Patch #2 affects, 
but I've never bothered to take the time to verify it either. My own 
installation has both patches now.
