Let's assume that's the case, although it may still happen that, between
two top samples, the system could allocate a huge amount of memory and
hang. And it's not that unlikely.

Check how much of free RAM you have compared to the high thresholds of
free memory reported at boot.

do you mean what vm_page reports at the earliest stages of boot?
It says 751M in pages, 733M free

perhaps instead of top, should I check vmstat?
after boot and lokin, vm_stat reports 748M in size, 650M free

After loading aptitude, it tells me there are 535M free. Just before hang, I see 526M free and it remains there with "total progress" not even starting and nothing to do (since the system was freshly upgraded with apt-get, I just removed a package, thus there was nothing to download)

Should I check memory differently? at a glance, I don't think we are going out of mem here.

The local console (hurd-console, not the mach console) was very recently
fixed [1] with regard to paging.

either it is not landed yet into debian, or I did have it already: I just upgraded with apt-get and saw no updates to console.
