Comment:

 Ok, i think it should be about ready now;

 I've added error handling (raises a SessionError containing the lowlevel
 error message), and added tests. There is an interface to set timeouts
 now; but rather than add an optional argument to everything that might
 send a message, you can set it on the session object itself, in which case
 the value will be used for any blocking read.

 I also added timeouts to the python version, though in this case no
 exception is raised (but the answer and envelope are None). Should we have
 an exception here too (ie if (blocking and timeout and no answer) raise
 TimeoutError)?
