>Description:

On ia64, at least on  r237134 and r235474,
/usr/bin/csup works fine (I use it exclusively
to update the ports tree) until this stage: 

Shutting down connection to server

After that it sits indefinitely in sigwai state,
and never exits, e.g.:

  PID USERNAME    THR PRI NICE   SIZE    RES STATE   C   TIME   WCPU COMMAND
33822 root          2  20    0 37496K 23352K sigwai  1   0:32  0.00% csup


Due to this it's hard to use csup in scripts.

>How-To-Repeat:
	
>Fix:

Following suggestions, I tried the current csup
code from https://bitbucket.org/mux/csup. This makes
no difference.
