IMHO, the main problem with threads is that they cannot be "paused" at
arbitrary moment. So, without sprinkling too many `thread-yield', any
serious computation makes the main command loop unusable.

Org mode has asynchronous processing since before threads were
introduced, using idle timers. It works seamlessly, but only thanks to
carefully balanced `org-element-cache-sync-idle-time',
`org-element-cache-sync-duration', and `org-element-cache-sync-break'
that limit how aggressively the background async computation is fired.
