Two further comments:

  1. If I run your code unmodified, I get the private working set as 115MB (with the Virtual Size: 210MB).

    But if I modify BlockSize => 104857600 (100MB) to BlockSize => 1024**2 (1MB), then the PWS falls to 14MB (VS:108MB).

    So basically, 92% of the PWS size is down to the 100MB buffer you've requested.

  2. However you are measuring this on Linux, it's lying to you. (Or ignoring your request for a 100MB buffer.)

    You can't have a process with a 100MB buffer only occupying 15MB.

You need to ensure that you're comparing apples with apples; which you evidently aren't yet.
