> RPC.waitForProxy swallows any attempts to interrupt it while waiting for a proxy; this makes it hard to shutdown a service that you are starting; you have to wait for the timeouts.
> There are only 4-5 places in the code that use either of the two overloaded methods, removing the catch and changing the signature should not be too painful, unless anyone is using the method outside the hadoop codebase.
