Removing file on host does not remove on guest

[bbodenmiller]

When I remove a file from my host OS folder it does not properly show up as removed in my guest OS.

vagrant@vagrant-ubuntu-trusty-64:/vagrant2$ ls -lah
total 51K
drwxrwxrwx  1 root root 4.0K Apr 20 08:43 .
drwxr-xr-x 24 root root 4.0K Apr 20 08:39 ..
-rwxrwxrwx  1 root root  275 Apr 20 07:42 Gemfile.lock
drwxrwxrwx  1 root root 4.0K Apr 20 08:42 .git
-rwxrwxrwx  1 root root  409 Apr 17 08:34 .gitignore

After removing .gitignore from host OS.

vagrant@vagrant-ubuntu-trusty-64:/vagrant2$ ls -lah
ls: cannot access .gitignore: No such file or directory

Running Vagrant 1.7.2 on Windows 8.1 with latest vagrant-winnfsd release. Guest OS is Ubuntu 14.04.

I've already done a fairly extensive search online to see if this could possible be a setting issue in the guest OS but have not found anything that could help. One option may be to try NFS4 but it does not appear this plugin supports that yet as vagrant up returns errors when I set nfs_version: 4.
