Comment:

 This works on trunk:

 {{{
 framework 'cocoa'
 framework 'macfuse'

 class Exception
   def to_ns(domain='', code=self.hash)
     user_info = {
       'NSLocalizedDescriptionKey' => self.message, 'Backtrace' =>
 self.backtrace
     }
     NSError.errorWithDomain(domain, code: code, userInfo: user_info)
   end
 end

 class HelloFS
   PATH = '/hello.txt'

   def contents(path)
     [PATH.lastPathComponent]
   end

   def read_file(path)
     return nil unless path == PATH
     "Hello, World!\n"
   end

   def size(path)
     read_file(path).size
   end

   def file?(path)
     path == '/hello.txt'
   end

   def contentsOfDirectoryAtPath(path, error: error)
     self.contents(path)
   rescue Exception => e
     error[0] = e.to_ns('GMUserFileSystemDomain')
     nil
   end

   def contentsAtPath(path)
     self.read_file(path).dataUsingEncoding(NSUTF8StringEncoding)
   end
 end

 d = HelloFS.new
 fs = GMUserFileSystem.alloc.initWithDelegate(d, isThreadSafe: true)
 fs.mountAtPath("/Volumes/Hello", withOptions: ['rdonly',
 'volname=HelloFS'])

 sleep 1

 puts `ls /Volumes/Hello`
 puts `cat /Volumes/Hello/hello.txt`

 fs.unmount
 }}}

 Outputs:
