I wasn't able to find the answer to your question in the official Deno documentation. However, based on the general behavior of serverless platforms and message queue systems, it's common for listeners to have some form of timeout or resource constraints, as this helps manage system resources effectively.
Please note that this advice is not based on the Deno documentation, and I would recommend double-checking the accuracy of this information. For the most accurate and up-to-date information, you might want to explore the Deno Deploy documentation further or reach out to the Deno community or support channels for clarification.
