#952 BrokePipeError when terminating Strata on Linux

本文

After Ctrl+c to terminate the engine i get:
```
[strata] stopping (Ctrl+C again to end the engine at once) ...
Traceback (most recent call last):
  File "/home/mike/Programs/Strata/serve/server.py", line 4129, in main
    time.sleep(1)                               # Windows never delivers Ctrl+C to an untimed Event.wait()
    ^^^^^^^^^^^^^
KeyboardInterrupt

During handling of the above exception, another exception occurred:

BrokenPipeError: [Errno 32] Broken pipe

During handling of the above exception, another exception occurred:

The engine itself runs great! Here is my setup:

Strata v0.1.39
Ubuntu 24.04.5 LTS
Intel® Core™ Ultra 5 245K
64Gb RAM
2x RTX 5060ti 16Gb (used --gpus 0,1), RTX 3060 12Gb (not used)
