Antoine, I think this would be the answer. Each test would be a bit
slower, because I would launch a new python process per test, but I
could run 16 tests in parallel (I have 16 CPUs and, actually, most
tests are not CPU intensive). I sorry to bother you with these details
and waste of time, but could you possibly change my buildbot
configurarion to launch, let's say, 4 test processes in parallel, just
for testing?.

Another option would be to have a single Python process and "fork" for
each test. That would launch each test in a separate process without
requiring a full python interpreter launching each time. Is this the
way "-j" is implemented, or is "-j" something external, like "make -j"?.

BTW, the (nice and helpful) OpenIndiana folks have told me a few hours
ago that they would increase my swap limit to 16GB. I am now waiting
for this change to be done.

I want my six builds in parallel (2.7, 3.2, 3.x, in 32 and 64 bits) back!.

Sorry for wasting your time with these mundane details...
