Not necessarily, "softlimit -d" only limits the data segment, not the
code size.

That's exactly what I did, before the one with softlimit (with identical
results)... though I posted only the latter, as it was the "most strict"
of the two.

I guess those are pretty standard "out of the box" FreeBSD values, as I
didn't change any of that.

AFAIK not including swap ("resident" should mean "in real memory").

I will do more tests and let you know...
PS: I wonder if that testcase has something to do with this, or if it
would hit the next one if that one wasn't active... I'll try to check.
