server.builder.ServerBuilder.dispatch_limits(mut, limits: DispatchLimits) -> Self
```

Bound how many commands may run at once.

Each one is a tmux client process with its own pipes and reader tasks,
and tmux serializes them on the far side anyway, so past a point more
clients buy queueing rather than throughput. A caller that fans out
wide -- an agent, a reconciler sweeping every pane -- otherwise turns
its own concurrency into pressure on the machine.

## Example

```rust
use libtmux::DispatchLimits;

let server = libtmux::Server::builder()
    .dispatch_limits(DispatchLimits::default().max_in_flight(4))
    .build()?;
```
