I was saying today that there are probably 100 people running i386 with i386
kernels with more than 16gb ram in the world. And then corrected myself to
"1000"…

because there are up to ten builds running simulataneously on these machines.
5 on average, and usually between 3 and 7 I'd say…

And hey, it used to work nicely.

(As a workaround I plan to use 8 machines with 15gb ram instead of 4 with 35…)
