Use graceful-fs

[blond]

Hi!

I know that graceful-fs was removed because of monkeypatching (#71).

But since v4 graceful-fs this has been fixed:

Do not monkey-patch the fs module. This module may now be used as a drop-in dep, and users can opt into monkey-patching the fs builtin if their app requires it.

Why do I need graceful-fs?

I'm developing the tartifacts package. It uses glob-stream to find files by patters.

if run tartifacts for project with a large number of files, then glob fails (yandex/tartifacts#58):

Error: ENFILE: file table overflow, open

To fix this I have to do strange things using proxyquire:

const globStream = proxyquire('glob-stream', {
    'glob': proxyquire('glob', {
        'fs': require('graceful-fs')
    })
});

Why not call gracefulFs.gracefulify() in project?

In most cases, we can do that:

const realFs = require('fs');

const gracefulFs = require('graceful-fs');
const tartifacts = require('tartifacts');

gracefulFs.gracefulify(realFs);

tartifacts();

But tartifacts run glob-stream in different processes (yandex/tartifacts#40).

Alternatives

if there is another reason for which glob can't use graceful-fs need to be able change fs with options (#280).

Definitely not going to go back to pulling in graceful-fs. Same answer as #280, add it to PathScurry, and glob will get it for free.
