Merge lp://staging/~jkakar/storm/better-timeout-messages into lp://staging/storm

Looks great to me. I don't know the code well enough to spot any flaws :)

The TimeoutTracer docstring could be a little clearer in the first sentence.

Perhaps

"""Provide a timeout facility for connections to prevent rogue operations.

...
"""

Thanks Rob, I've updated the docstring to what you've suggested.

Hi, this looks fine and a clear improvement.

Is there any chance that changing the signature of TimeoutError.__init__ will break client code? It does seem unlikely, but I thought it was worth asking :-)

Michael:

I wondered about the changes to TimeoutError.__init__ breaking
client code, too. The sense I have is that it would be fairly odd
for client code to use what is basically an internal Storm exception
type. I suspect that any non-Storm code using it is doing something
funky that we don't need to worry about supporting.
