│ Warning
  │
  │  It is strongly encouraged to favor Threads.@spawn over @async always even when no parallelism is required especially in publicly distributed libraries. This is
  │  because a use of @async disables the migration of the parent task across worker threads in the current implementation of Julia. Thus, seemingly innocent use of
  │  @async in a library function can have a large impact on the performance of very different parts of user applications.
