You didn't send HTML format (and please don't!) and the lines did
wrap, but that's OK, it is obvious, and easy to deal with (no more
than a minor annoyance - nothing like as bad as HTML would be, which
I wouldn't attempt to read at all).

Yes.

Sorry, can't help with that, I am a gdb novice (once used much
better debuggers, and could never really fathom gdb for more than
fairly trivial stuff) - certainly I've never even attempted to use
gdb that way to attach to a running process.   But even if it did,
unless everything was compiled with -g (which it almost certainly
isn't - everything in this case means emacs, and all the libraries
it uses) the help it would offer would probably not be all that
much.

But you didn't do what I asked, run

	ps -ls -p 1107
	ps -ls -p 4180

and find out what threads exist in each process, and the state of
all of the threads, that might reveal more to someone.

But if what Martin said is correct, and it almost certainly is, this
is an ancient sparc multi-cpu problem, that no-one has been able to
find so far, so the best option might simply be to kill things once
they have reached this state and start again (without cleaning anything).
