Consider: runner-to-giver message queue

[Vectorial1024]

While this is a hands-off library for async PHP code execution, and the task runner generally works independently from the task giver, it seems a good idea to allow an easy-to-use one-way communication from the task runner to the task giver. In effect, this would be a poor man's IPC (inter-process communication) that also works in Windows, which will be very well-received since Windows does not have any obvious equivalent feature compared to the Unix (native) IPC.

With this, tasks that are normally stuck with a single core, but is quite parallelizable can be upgraded to support concurrency. One such library would be (self-advertisement) vectorial1024/laravel-cache-evict (external-link).

Think about it.

This feels like something out of scope of this library. Supposedly, other libraries can also make use of this feature for their own purposes, and then it is best to extract this "feature" as a separate library.
