Removed unnecessary try/except and cleaned for some PEP8

[Lawouach]

Hello,

I'm not quite sure it was a useless try/except clause. As it stands, in your code the ws object may never removed from the pool. Is that expected?

I don't quite understand what you mean. These lines

if ws:
    self.server.pool.track(ws)

will be reached in the old and new implementations only if there were no exceptions in the first 3 lines, because of this:

except:
   raise

[Lawouach]

Damn. I somehow read finally rather than else on the try/except. You are right.

[warvariuc]

Maybe there should be some logic using finally but I am not aware of it.

I think I need to spend some time trying to identify the key issues with error handlings and related cleanups.
