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

289 | reentrant. Thus "blocking" it by e.g. waiting for I/O is not acceptable. |
|
|
290 | |
|

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