-------------------------------------
If you don't see a need for this either, yes, lets close it.
I was hoping you had something in mind :)
> Add thread that detects JVM pauses

> Long JVM pauses can cause Kafka malfunctions (especially when interacting
> with ZK) that can be challenging to debug.
> I propose implementing HADOOP-9618 in Kafka:
> Add a simple thread which loops on 1-second sleeps, and if the sleep ever
> takes significantly longer than 1 second, log a WARN. This will make GC
> pauses (and other pauses) obvious in logs.
