process in the background when entering a repository, and displaying
some marker ('??' maybe) in the prompt instead of the dirty-state info
until git-status has finished.
This is somewhat interesting.
Perhaps we can introduce a helper binary that does what __git_ps1()
does, with a --timeout=500ms option to say "I dunno (yet)", and keep
priming the well in the background when it takes more than the
specified amount of time?

That would be nice. My fork-fu is weak, so I cheated and relied on
kill/timeout instead.
I have had this code below in my zsh git prompt (based on oh-my-zsh)
for more than a year. It uses $(timeout) to kill the status command
if it does not complete in 1 second. It's dumb in several ways, but
it does show me four different flags fairly reliably indicating
whether I have changed files, untracked files, clean workdir, or I
timed out trying to find out.
git_dirty_timeout () {
#-- Modified files
xx=$(timeout 1s git status -s $@ 2> /dev/null)
test $? -eq 124 && return 124
test -n ${xx} && return 50
#-- Untracked files (only)
xx=$(timeout 1s git status -s -uno $@ 2> /dev/null)
test $? -eq 124 && return 124
test -n ${xx} && return 51
return 0
}
