As I said before, I don't think the problem is with mpirun or
asc_schedule, but with our ptmalloc code, which is why it appears to
work with the latest beta releases for Jeff and I. If there is
another problem, we would like to know what it is, and generally are
willing to take patches that fix issues relevant to the community as
a whole.
