I was mistaking a test program taking a LONG time to run with failing.

FYI - the test program was the the threadLock test that is part of Zope
http://www.zope.org

Other good news is that Zope compiles out of the box with
the newest binutils release < enable-autoexports > and recent snapshots.

Seems to run too, but I am doing more testing, and do not want to broadly
announce this until we have determined the cause of Jason's problem  :-)

Cheers

Norman
