@squakez, I tried with 4.9.0-SNAPSHOT. I wouldn't say it's fixed, it's just
... different. My reproducer goes as follows:
```java
from("netty-http:http://0.0.0.0:12345";)
.routeId("netty")
.log("in netty route")
.to("direct:aSlowerRoute")
.to("direct:aFasterRoute");
from("timer:mytimer?period=5000&repeatCount=2&synchronous=true")
.routeId("timer")
.log("in timer route")
.to("direct:aSlowerRoute")
.to("direct:aFasterRoute");
from("direct:aSlowerRoute")
.log("in aSlowerRoute")
.delay(simple("${random(50, 350)}"))
.log("still in aSlowerRoute");
from("direct:aFasterRoute")
.log("in aFasterRoute")
.delay(simple("${random(10, 70)}"))
.log("still in aFasterRoute");
```
And here are the logs:
