LO Problem List (Can we get one)

Greetings once again. I've been following recent threads on problems with
large objects and the possibility of plans for unlimited-size tuples in
version 6.6 (as a replacement). I was wondering if there was a list of
all the Large Object known problems/limitations/drawbacks as of 6.5.
This would include everything from any remaining memory leaks to the
performance hits resulting from having all the files in one directory to
the lack of a way to get a list of all existing LOs for dumping (or
cleanup). I like to think I've caught all the relevant concerns (I use
Large Objects extensively in a large application I will be deploying) but
it would be nice to have such a list as well as perhaps linking them to
the documentation.

Thanks...
