Xcode Hangs When Attempting To Open A Named Pipe

Summary:
This is a followup to rdar://28666836.  I was attempting to test whether this Radar was fixed by adding a named pipe as a resource on Xcode 9 beta 1, but managed to make Xcode hang instead!  To make things interesting, when adding a named pipe to an Xcode 9 project, Xcode now makes such named piped visible when you attempt to add them in a project.

Steps to Reproduce:
1.  Create a single view iOS project in Xcode.  
2.  Create a new folder in your project directory, whether under Finder or a terminal.
3.  Navigate to your new folder in a terminal & run these commands one after the other.

mkfifo my_pipe
gzip -9 -c < my_pipe > out.gz &

4.  Still in the terminal in your newly created folder, for the sake of comparison, add a random 1024 byte binary file using this command:

head -c 1024 </dev/urandom > bfile.dat

5.  Drag your newly created folder into Xcode.

Expected Results:
I expect to see an icon in the editor area matching the filesystem entry on Xcode, as happens with any file Xcode can’t read like bfile.dat.
