--- Comment #6 from Shyamsundar <srangana at redhat.com> ---
@Niels: The MT epoll patch does break the throttling, so we need to get that
fixed.

Reverting the MT epoll would not help, as that would take us backwards. With MT
epoll there are going to be edge cases of races in other parts of the code, the
only way to scrub them and get things moving would be to fix them, so I am not
for reverting the epoll patch at all.

On the investigation front, I would say that is complete, we need a fix for the
same that does not seem trivial or in line with the previous approach of
throttling the readers, we may need to throttle the writers.
