Ismael Juma commented on KAFKA-2419:
------------------------------------
[~aauradkar] [~jjkoshy] We are creating one thread per `Metrics` instance and
we create one `Metrics` per consumer and per producer. Do we really one to
create one garbage collection thread per consumer/producer?
Also, I can't find any usages of `ExpireSensorTask` outside of tests:

What am I missing?
