| 333 | // and a positive number is used as a timeout in milliseconds that limits the |
| 334 | // time spent waiting between receiving output characters from the program. |

| 336 | // milliseconds on the total running time of the program. Exceptions are |
| 337 | // thrown on timeouts or other errors or if the exit status of the program |
| 338 | // indicates an error. |

| 341 | // exception/ on error. |

| 343 | // os.setenv(variable, value) sets an environment variable. Repeated calls to |
| 344 | // this method leak memory due to the API of setenv in the standard C library. |
