		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
		195	fast or be very important.
