Hello Andreas. It means I do this:

grep Committed_AS /proc/meminfo

to see how much memory I need.

I first measure it before the build begins, and then I measure it
during the build and substract the initial value. This is how I try
to estimate the amount of memory required to build a given package.

In this case (python-ruffus), it used to be 18 GB for version 2.7,
which made it to be the most memory demanding package in buster so far.

Now in version 2.8.1-3 and 2.8.1-4 I get 38 GB which is a lot worse.

A simple loop like this during the build will work:

while true; do grep Committed_AS /proc/meminfo; sleep 1; done

Thanks.
