It will all go horrible wrong if you do this. If you are already
running an Emacs, I presume that you want to read in batch because
emacs hangs while reading? In which case, you might want to use the
gnus-demon instead which will read in the idle cycle. You might also
want to look at the nnmaildir backend which is supposed to cope with
concurrent modification. Never tried it, although I mean to at some
time.
