Still failing.  Ok I take that back.  There was two places with (+ 
(current-time) 2).  After changing the other one it is *not* failing.

This message I think I never see when running the test directly.  Only with 
"make check" do I see it.  Yeah, three times in a row with make check, never 
with ./check-guile threads.test.

I'm running 7.2alpha5 libgc.  From that tarball I think, not cvs.
