async.el starts slowly, has no good way to read the current state
like text properties or buffer content, has no knowledge about loaded
libraries and incurs double serialization overhead. If just a Hello
World needs 70ms on my system imagine what it's like doing something
with org. That is far from ideal.
For context: I am mostly thinking about passive work in my treemacs
package that happens without any user interaction, like re-rendering on
changes in the file system or a file's tags, passively fontifying files
based on their git status after some directory node has been opened or
following the file the user is currently editing. All of that happens
passively, so I consider any perceptible delay a no-go. Being able to
just stop the git-fontify when the user types and later pick it up would
be a major help.

Yielding doesn't work for me, my input is ignored most of the time. I
will make my code emacs-q ready and open a bug report for it tomorrow.

Same for me I'm afraid.
