```
io.github.libtmux.Channel.Channel.awaitReservingCapacity(timeout: Duration) -> WakeReason
```

Waits while preserving process capacity for a call through this server that signals it.

Use this when the waiter and its release share a bounded transport. A wait released outside
that transport should use {@link #await}; reserving capacity for it only rejects useful
concurrency.

## Raises

- `io.github.libtmux.transport.TmuxTransportException`: if the wait could not be dispatched
- `InterruptedException`: if the waiting thread is interrupted, which is a cancellation rather than a timeout and so is not reported as one
