Inability to connect to Elvin server on OS X throws exception

[chris]

When Eddie on OS X cannot connect to the Elvin server it throws the exception below. The Elvin module should be able to handle this more gracefully and continue to retry, like it does on other platforms.

Exception in thread Elvin Dispatcher:Traceback (most recent call last):
  File "/System/Library/Frameworks/Python.framework/Versions/2.3/lib/python2.3/threading.py", line 442, in __bootstrap
    self.run()

    raise error(EBADF, 'Bad file descriptor')
error: (9, 'Bad file descriptor')

If I manually try to connect to the Elvin server from the OS X host at this time, I get:

$ telnet elvin 2917
Trying 10.0.0.1...
telnet: connect to address 10.0.0.1: Connection refused
telnet: Unable to connect to remote host

Also, this exception is only output to the console (killing the Elvin thread, possibly) but needs to be caught and logged like most other exceptions.
