zsh-job-queue

zsh-job-queue manages global (cross-terminal) synchronous job queues.

It's useful if you you have a script that destructively modifies a file and you want to support running the script in multiple terminals in quick succession.

That's is a real need I have. zsh-abbr, my zsh manager for auto-expanding abbreviations, has common operations in which file contents are read, parsed, and modified, and the modified contents are written back to the file. Notably this happens when a user uses the zsh-abbr CLI to manage abbreviations, and when a new session is started. Without a cross-terminal job queue, it would be possible to mistime the actions (for example if a terminal was delayed but some OS process) and lose data. zsh-job-queue is not infallible, but in practice it's pretty close; and when something does go wrong, the console logs help users determine whether it was user error or a bug.
