188The design of crossfire+ requires that the main coro ($Coro::main) is
189always able to handle events or runnable, as crossfire+ is only partly
190reentrant. Thus "blocking" it by e.g. waiting for I/O is not acceptable.
191
192If it must be done, put the blocking parts into C<sync_job>. This will run
193the given BLOCK in another coroutine while waiting for the result. The
194server will be frozen during this time, so the block should either finish
195fast or be very important.
