File descriptor issues with Mocha in ElementaryOS

[josiah14]

It seems mock-fs can't create the mock filesystem correctly in ElementaryOS??? This code works fine on OSX.

Mocha and Chai.expect are being used, here.

The test:

  /*
   * ::getFtpFileList
   */
  describe('::getFtpFileList', function () {
    var mockfs = require('mock-fs'),
        fs = require('fs');

    describe('When the directory contains only files', function () {
      before(function () {
        mockfs({
            'test': {
              'file.txt': 'contents',
              'file1.ext': ''
            }
        });
      });

      after(function () {
        mockfs.restore();
      });

      it('Injects a String Array of all the files with their full paths', function () {
        functions.getFtpFileList('test', function (err, files) {
          expect(files).to.deep.equal([
            'test/file.txt',
            'test/file1.ext'
          ]);

          expect(err).to.equal(null);
        });
      });
    });

The error

I am seeing this error at fs.write in one setup of Windows 7. Also a similar EBADF error in a Windows 8 setup, though from fs.close.

Also having this problem when using fs.readFileSync on Linux.

On Windows 7, I'm getting EBADF too. Just calling mock() throws this error. Also, mock({'path/to/dir': {}}) throws same error.

What node versions are you all running? I get this on 10, but not on 8.
