Thanks for this stack trace Manoj. I think I understand what is happening now.
What happens is, while a write is in progress if more writes come, they will be
put in a queue which will be picked up as soon as the previous write completes.
So because epoll-thread resumes the write, it is doing encoding. So yes, you
are correct, in this case it is happening in epoll-thread. Do you think this is
bad. Is it becoming a bottle-neck?
