offending system call fail with EFBIG instead of terminating the
process.

LGTM apart from a variable name in the test.

const cmd = `ulimit -f 1 && '${process.execPath}' '${__filename}' child`;
const result = child_process.spawnSync('/bin/sh', ['-c', cmd]);
assert.strictEqual(result.stdout.toString(), '');
const shibboleth = 'Error: EFBIG: file too large, write';
