Well, I am just curious how critical it is to get it resolved and is 
there any way to avoid ABI breakage. Software compiled for 9.x won't run 
on 10.x even when fitted with the proper compat libs, as far as I can 
tell and not all software can be easily recompiled.

There are also other places where BSD have subtle differences with 
almost any other nix flavor out there. Not accepting sun_len = 0 in the 
unix domain sockets is one of those places that comes to mind. Other 
systems just do strlen() of sun_path, while BSD does EINVAL. And we've 
been living with this for decades.
