Revert of Allocate memory in smaller chunks for chrome://memory-exhaust/

Revert of Allocate memory in smaller chunks for chrome://memory-exhaust/ (patchset #1 id:1 of https://codereview.chromium.org/2882513003/ )

Reason for revert:
This fixed the test in one build configuration but made it hang in another one instead (see bug).

I'll come up with a less magic and more effective fix.
