Getting this error when I use pssh with -i, -h and a filename with servers 
specified:

It was working just fine in 2.1.1, but broken since then.

Hmm.  I had thought that siginterrupt had been around for a while, but after 
seeing your bug report, I checked and noticed that it was added in Python 2.6.  
I should probably add a check to only run that line if siginterrupt is 
available.

What version of Python are you using?  What distribution are you running?  We 
should probably still support Python 2.5, but it would be helpful to know where 
older versions are being used.  Thanks.

Hmm, apparently I am still using Python 2.5.2 on this specific server.
This is the latest version used in Debian 5.0.8 (Stable)

Most of the "enterprise" distributions use older than 2.6 versions of python as 
shown by :

  RHEL4 (2.3.4) : EOL Feb 2012
  RHEL5 (2.4.3) : EOL Mar 2014
  Debian5 (2.5.2) : EOL ~Feb 2012
  Ubuntu 8.04 (2.5.2) : EOL Apr 2013

Attached patch tested in Debian5 to avoid this traceback

Thanks for the info about which Python versions are being used by enterprise 
distributions.  Since RHEL5 is still being supported until 2014, we should 
probably keep supporting Python 2.4 for a while.

Thanks for the patch. This is rather a small change, but is working just fine!
Hopefully they'll finally release Debian 6 soon, so we can have a bit more 
up-to-date Python there.

This should be fixed in 2.2.2.  Thanks.
