When unloading, ld.so removes elements from grpref list too soon, not

Patch:
Your patch reverts this commit:
----------------------------
revision 1.34
date: 2011/07/13 20:49:44; author: drahn; state: Exp; lines: +4 -2;
Delete items on grpreflist when walking them to decrement the count,
otherwise double decrement can occur. ok kurt@ timeout on other reviewers.

I'm not sure if there's a regress for the issue Dale was fixing, but
simply reverting his fix and reintroducing the original problem isn't much
better than where we are now.
I'll stare at this some and see if I can see how to avoid leaving group
leaders on the global list...
Any update on this?
