I'm now running my node with this patch (PR through ea98832), and it's looking good. It may be too early to say yet, but I am not seeing the continual run-up in memory usage by |

It's still looking great. I'd call this one licked. |
When we moved gossip filtering to connectd, this aging got lost. Without this, we hit the 10,000 entry limit before expiring full gossip anti-echo cache. This is under 1M in allocations per peer, but in DEVELOPER mode each allocation includes adds 3 notifiers (32 bytes each) and a backtrace child (40 + 40 + 256 bytes), making it almost 10MB per peer, plus allocation overhead.

channeld is the only user of these functions, since it now streams all gossip itself. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
It was doing its own equivalent check anyway. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
Instead of doing an allocation per entry, put the entry in directly. This means only 30 bit resolution on 32-bit machines, but if a bit of gossip gets accidently suppressed that's ok. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
10,000 per peer was too much. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>

This may not be the only leak, but it's one.
