Just tried this:

gvim -u NONE -N -p fileA.txt fileB.txt
:so [path]/Detach.vim
:Detach

and it worked correctly without any messages. The message you got
appears when you hold the file open in another instance of gvim and,
really, you don't want not to have it. Its telling you that changes
made to the file in one instance of gvim won't necessarily be reflected
in the other instance. Remember, the :Detach command starts up a new
instance of gvim; its not a separate thread sharing the same memory.
Vim does not support that.
