## Workarounds

1. **** (95% success)
   ```
   go func() { ch <- data }(); result := <-ch
   ```
2. **** (90% success)
   ```
   select { case ch <- data: default: /* handle timeout */ }
   ```

## Dead Ends

- **** — Only postpones the problem; buffer fills up eventually. (60% fail)
- **** — Sleep does not fix the root cause; may cause indefinite blocking. (90% fail)
