248 | always able to handle events or runnable, as crossfire+ is only partly |

249 | reentrant. Thus "blocking" it by e.g. waiting for I/O is not acceptable. |
|

250 | |
|

|
|
252 | the given BLOCK in another coroutine while waiting for the result. The |
|
|
253 | server will be frozen during this time, so the block should either finish |
