Avoid recursive calls to RLock()
Topology calls itsel recursively invoking RLock. This, according to go
documentation is wrong. This commit moves the body of Topology function
to a non-thread safe unexported function to keep locsk at check!

Handle Accept errors gracefully.
Originally when Accept fails we log the error and let the program flow
continue. This can lead to us spawning handling connection go routines
on nil connections which in turn leads to Go panics.
