Hi,
this patch fixes a bug I've found while debugging a failure reported
by Yi Zhang [1].

This patch seems to make that failure disappear [1]. Yet it was tested
only together with other debug patches (which add logs and invariant
checks), so I don't know whether the other patches influenced the
outcome as well. At any rate, this patch does fix a bug.

Thanks,
Paolo
