Meh...passed on SmartOs 15 64-bit, but barely didn't time out:

ok 1255 sequential/test-buffer-creation-regression
  ---
  duration_ms: 58.896

Will try splitting the test up into three files.

OK, split the test into 3. Trying again...

These results seem more like it:

ok 1255 sequential/test-buffer-creation-regression-1
  ---
  duration_ms: 0.428
  ...
ok 1256 sequential/test-buffer-creation-regression-2
  ---
  duration_ms: 9.35
  ...
ok 1257 sequential/test-buffer-creation-regression-3
  ---
  duration_ms: 16.939

CI is all green ✅ . I'd like to expedite landing this because this issue is significantly impacting CI results. Reviews, anyone? @nodejs/testing @thefourtheye

@Trott All the three tests have more than 90% similar code. Can we refactor and put the common code in one file?

Apart from that, I believe the second test itself is enough as regression. Can we modify the original test and remove other two cases?

For me, at least, running v7.2.0, only the final test case fails. Happy to get rid of the other two and just keep that one, if that works.

test-buffer-creation-regression is flaky on some SmartOS hosts in CI,
timing out. Move to sequential so it does not compete with other tests
for resources. Reduce three test cases to just the one needed to
identify the regression.

Reduced to just the one test case needed. CI: https://ci.nodejs.org/job/node-test-pull-request/5286/

This is failing when backported to v4.x

is that expected behavior?

test/parallel/test-buffer-creation-regression.js doesn't exist on v4.x-staging, does it? If not then this should be labeled do-not-land-on-v4.x I think...

@Trott this is failing on v6.x too. labelled don't land, feel free to backport

Seems like the original test doesn't exist on v6.x either, so yeah, do not land on v6.x.

I backported this in #11176, along with #9815 (which has the test) and added lts watch v6.x.
