brew --jobs auto still (a bit) broken

brew doctor output

all good

Verification

• I ran brew update twice and am still able to reproduce my issue.
• My "brew doctor output" above says Your system is ready to brew or a definitely unrelated Tier message.
• This issue's title and/or description do not reference a single formula e.g. brew install wget. If they do, open an issue at https://github.com/Homebrew/homebrew-core/issues/new/choose instead.

What were you trying to do (and why)?

Trying to install tmux & tpack
This is related to the other two defects (#22293 and #22837) I raised against --jobs auto

What happened (include all command output)?

 Installing tmux
  Installing tpack
  Error: A `brew install --cask tmuxpack/tpack/tpack --adopt` process has already
         locked /home/linuxbrew/.linuxbrew/Cellar/linux-headers@6.8.
  Please wait for it to finish or terminate it to continue.
  Installing tpack has failed!
  `brew bundle` failed! 1 Brewfile dependency failed to install   (exit 1)

What did you expect to happen?

tmux and tpack installed

Step-by-step reproduction instructions (running brew commands)

brewfile contains


brew "tmux"
cask "tmuxpack/tpack/tpack"

@MikeMcQuaid hi, the recent fix does not appear to have fixed the issue - could you have another look please.

It's better in that it now exits with non-zero status, but the lock issue persists.

I assume this is a general issue. I have a reasonably large Brewfile but this is currently the only package that's failing like this.

MRE - it fails in brew's docker image

docker run --rm homebrew/brew bash -lc '
brew update >/dev/null
printf "%s\n" "brew \"tmux\"" "cask \"tmuxpack/tpack/tpack\"" > Brewfile
brew bundle install --jobs auto --file=Brewfile
'
