Why that may affect 'screen' I have no idea.  Does not seem to be a
likely cause but I cannot really tell.  OTOH the above _may_ mean
that your disk is acting up (and possibly swap is affected).  If that
is really the case then you should get quite a lot to read in
/var/log/messages and in dmesg output.

If this is not the case  then running
 
   strace -o /tmp/screen.trace screen

and looking at results may give you some clues (but you have to
be careful how you read that and pay attention to a context).
