When using the curses ui with the CVS version as of 4/28/2006 with
Python 2.4.3, lyntin disconnects if I resize an xterm:

! socket exception
! Traceback (most recent call last):
!   File "/usr/lib/python2.4/site-packages/lyntin/net.py", line 369, in run
!     newdata =3D self._pollForData()
!   File "/usr/lib/python2.4/site-packages/lyntin/net.py", line 328,
in _pollForData
!     readers, e, w =3D select.select([self._sock], [], [], .2)
! error: (4, 'Interrupted system call')
!
# Session genesis disconnected.

I've attached a patch that fixes the problem. I'm not sure if its the
cleanest way but it seems to work fine.
