1) Each relay request expires after 5 seconds, after which nodes will stop relaying it, preventing any kind of infinite loop. So it has to reach the destination peer within 5 seconds. This should be fine, because the original peer's request would timeout anyway, so there's nothing to be gained by continuing to relay it. 2) Each relay request stops being forwarded after 3 "hops" - i.e. once it has been relayed through 3 different peers, it will no longer be transmitted any further. If we assume that each node has 16 connections, that allows it to reach a theoretical maximum of 4096 peers in 3 hops. In practice it will be less, and may not reach everyone due to peer "islands". But it will automatically retry a few times on a timer, so should hopefully find what it needs eventually. Plus, it still has the ability to make a direct connection to anyone hosting the data, as long as they are port forwarded.
