Parcel (or analog) to data exchange between Parent and Child processes

Hello there! 👋 It's not an issue, rather a question 🤗 I have a worker pool with some tasks running. Workers are using consumables they may request at any time and any number of times. Ideally, I wish to use Parcel for this purpose. Parcel is a very convenient way of communicating with data, but it can't be serialized and thus you can't pass it to Task. There's also Channel, but I don't understand how to use it in more complex cases than the docs described (when you sequentially send value, receive value, return result). How to solve my challenge without crutches? Thanks!

The issue names no files or tests; begin by reading the documentation for Parcel, Task, and Channel and tracing how the worker pool communicates between parent and child processes. Clarify the supported data-exchange behavior and define what a complete solution would need to demonstrate, since the issue currently asks a question rather than specifying a change.
