Race condition under Windows

[Cito]

When running the following under Windows, I sometimes get an EPERM error:

var fs = require("fs")
var fsvacuum = require("fs-vacuum")

var options = {
  base  : ".",
  purge : true
};

function vacuum(path) {
    fsvacuum(path, options, function (error) {
        if (error) console.error("Cannot remove", path, error)
    })
}

fs.mkdirSync("foo")
fs.mkdirSync("foo/bar")
fs.mkdirSync("foo/bar/bax")
fs.mkdirSync("foo/bar/bay")
fs.mkdirSync("foo/bar/baz")

vacuum("foo/bar/bax")
vacuum("foo/bar/bay")
vacuum("foo/bar/baz")
vacuum("foo")

Apparently this can happen under Windows when concurrent lstat, readdir and rmdir operations are blocking each other - I noticed that the error can occur in all of these calls inside the next() function of vacuum.

The rimraf package contains an internal function fixWinEPERM that addresses this issue. Maybe something similar needs to be added to vacuum as well.
