Yes, this was being discussed in this thread:

  https://lists.gnu.org/archive/html/qemu-devel/2018-12/msg01638.html

I haven't heard from Eduardo in a while, I guess he's off for the
holidays.

My latest suggestion was to try a branch where test-qht-par is
standalone, instead of using system(3) to call qht-bench--see
this message:
  https://lists.gnu.org/archive/html/qemu-devel/2018-12/msg02056.html

Can anyone please try that? Or at least let me know how to run
a test Travis build so that I can debug this faster.

Thanks,

		Emilio
