Description of change

The test is memory intensive and times out occasionally on Raspberry Pi
devices in CI. Successful test runs take about 90 seconds, but the
devices time out after 120 seconds. That's not a lot of headroom. So
let's skip the test on devices that have only modest amounts of memory.

Doesn't there need to be a header here or something, like the other tests that have a similar skip message?

I'm not sure what you mean. Here's another example:

const skipMessage = 'intensive toString tests due to memory confinements';
if (!common.enoughTestMem) {
common.skip(skipMessage);
return;
}

And here's what this test pass when it skips:

1..0 # Skipped: intensive toString tests due to memory confinements

I guess I'll run CI and see what happens on the Raspberry Pi devices...

Nevermind, I didn't realize .skip() was adding the necessary header.

Only CI failure is known FreeBSD flaky test. (How is everyone not LGTM-ing the crud out of #7555 to get that fixed?)

Raspberry Pis in CI seem to skip correctly:

ok 45 parallel/test-fs-read-buffer-tostring-fail # skip intensive toString tests due to memory confinements
  ---
  duration_ms: 2.53

That output format matches other skipped tests, such as:

ok 64 parallel/test-http-full-response # skip problem spawning `ab`.
  ---
  duration_ms: 2.855

Meanwhile, the test is not skipped on (for example) OS X:

ok 322 parallel/test-fs-read-buffer-tostring-fail
  ---
  duration_ms: 2.336

I think this is good to go.

lgtm, seems like the sensible way to go

@thealphanerd Yes if it lands cleanly and CI passes.
