Oops, I forgot about that..although so did David when he removed
libc_r from 7.0 and broke sparc :-)

So I guess this is a libc_r missing feature.  Probably the solution is
to use libthr on 6.x too (I don't know if it works well enough on
5.x).  libthr causes witness panics under load on sparc64 though.
