Fix failure during accept(...)

Browse Source 
Motivation:

Sometimes accept failed as we not correctly set the active variable when constructing the server channel. This lead to the situation that we tried to add POLLIN before the channel become active and so tried to call accept before it was listen.

Modifications:

- Use the correct constructor
- Cleanup

Result:

No more accept failures.
