I'll do some experiments to verify... but my setup is two reliable servers and one non-reliable.
The two reliable ones are enabled. The other is 'optional' (but set to backup now). When the unreliable one is flagged as optional in beta4 and it times out, all the servers stop.
I'll try downloading something else now and see how it goes....
Below is what I am seeing in my log. Basically, it is failing to connect to the server, but not ignoring it like it used to for 'optional' servers. The client seems to sometimes download a small section of the queue, but then when it tries the unreliable server again it stops moving.
If I return the unreliable server to a 'backup' - all is well again. But I prefer the functionality of 'optional'.
