Performance: Unbounded queue growth can lead to memory issues

[m96-chan]

Summary

The async queue in \ has no maximum size, which can lead to unbounded memory growth if consumer is slower than producer.

Location

Problem

The queue is created without a maxsize, meaning it can grow indefinitely if:

• The async consumer is slow to process data
• User code doesn't call \ or iterate fast enough

Impact

• Memory can grow unboundedly in long-running capture sessions
• No backpressure mechanism to signal producer to slow down
• Potential OOM errors in constrained environments

Comparison with other backends

Linux backend correctly sets a bounded queue:

Suggested Fix

Add a reasonable maxsize to the queue:
