188 | The design of crossfire+ requires that the main coro ($Coro::main) is |
|
|
189 | always able to handle events or runnable, as crossfire+ is only partly |
|
|
190 | reentrant. Thus "blocking" it by e.g. waiting for I/O is not acceptable. |
|
|
191 | |
|
|
192 | If it must be done, put the blocking parts into C<sync_job>. This will run |
|
|
193 | the given BLOCK in another coroutine while waiting for the result. The |
|
|
194 | server will be frozen during this time, so the block should either finish |
