Can we wrap `wait` in publish under condition for first publish as it is no-op.

```
pub fn publish(&mut self) -> &mut Self {

+if !first {
self.wait(&mut epochs);
+}
self.update_and_swap(&mut epochs)
}
```
On first publish call, there are no readers on the w_handle, so we can just wrap that in `not of first`.

Start at the publish method shown in the issue and trace how the first publish call relates to wait, epochs, and update_and_swap. Verify that wait is skipped only for the first publish and remains active for later calls; done means the existing behavior is preserved while the first-call no-op is removed.
