A few thoughts on this (mostly based on my discussions with Ashesh):

1) You seem to have removed the poll delay. I assume that is to try to
avoid missing messages? Can we re-introduce the delay (to avoid
excessive network requests), but collect messages while we're waiting?

Using thread?

Start a thread during the timeout?

Not necessarily. If we want a 2 second polling delay, we could just sleep for 0.5 secs, collect messages, sleep for 0.5 sec, collect messages, <repeat...> return to client.

That's a very huge delay in practical.

We were hardly waiting for during poll (that was in milliseconds), but - still we were loosing a lot of the messages. (a lot more from the current implementation).

What was the original delay? Now there appears to be none at all.

That was 10 milliseconds
