Enabling blocking will cause the ring buffer to behave like a buffered [io.Pipe](https://pkg.go.dev/io#Pipe).

Regular Reads will block until data is available, but not wait for a full buffer. 
Writes will block until there is space available and writes bigger than the buffer will wait for reads to make space.

`TryRead` and `TryWrite` are still available for non-blocking reads and writes.

	return int(globalHTTPListen.Subscribers()) + int(globalTrace.Subscribers())
}

func waitForLowIO(maxIO int, maxWait time.Duration, currentIO func() int) {
	// No need to wait run at full speed.
	if maxIO <= 0 {
		return
	}

	const waitTick = 100 * time.Millisecond

	tmpMaxWait := maxWait

	for currentIO() >= maxIO {

```Python
with open("file.txt") as file:
    file.read()
```

En versiones recientes de Python, también hay un **async context manager**. Lo usarías con `async with`:

```Python
async with lifespan(app):
    await do_stuff()
```
