Hi Steven - First, the humor < http://xkcd.com/138/ >.

Do "ipcs -a" to see how many shared memory attachments are in place.  You might 
see a lot, given that 'shmat' returns 'too many files open'.  Here's the BASH 
script I run, very often in my work right now, to try to remove extraneous ones:

for tf in `ipcs -m | sed -e 1d -e 2d -e 3d | awk '{print $2 }'`; do
    ipcrm -m $tf ;
done

If all else fails, reboot and see if that doesn't take care of the issue, at 
least for now.  If the issue persists, it might be a new Lion issue from 
10.7.3; I know I've run GNU Radio in 10.7.[0-2].  I'll hopefully have a few 
spare cycles later this week to look into GNU Radio on Lion. - MLD
