thanks, it's good to know it's used in a large scale installation.

There are some fixes in the 2.5 code base that need porting to 2.4, I'll see 
what I can do about that in September. Mostly minor stuff about closing file 
descriptors (=unlocking) on error.

So those fixes could at least land on the 2.4 branch,
independent if there's going to be another release or not.
