|

187 | always able to handle events or runnable, as crossfire+ is only partly |
|
|
188 | reentrant. Thus "blocking" it by e.g. waiting for I/O is not acceptable. |
|
|
189 | |
|

190 | If it must be done, put the blocking parts into C<sync_job>. This will run |
|
|
191 | the given BLOCK in another coroutine while waiting for the result. The |
|

192 | server will be frozen during this time, so the block should either finish |
