urgent: undoing a cvsup update

[Aryeh Friedman]

I just cvsuped the latest sources and they break many programs named
and most X11-apps comes to mind immediately

Well how do I backout of the this.... keep in miond I use cvs-supfile
to populate a local repo and did a rm -rf /usr/obj /usr/src thinking
that might clear stuff up but it didn't

As far I can tell I can track the main issue to the new malloc stuff

All programs that are borken just hang immediatlely after invocation
