UNIXServer#closed? returns false after UNIXServer#close called

Description
When I tried the simple script below, ruby trunk works unexpectedly:
require 'socket'
server = UNIXServer.new('/tmp/yaaaay')
thread = Thread.new do
begin
while sock = server.accept
p(here: "accepted", sock: sock)
sock.close rescue nil
end
rescue => e
p(here: "rescue", closed: server.closed?, error: e)
end
end
sleep 1
server.close
sleep 1
File.delete('/tmp/yaaaay')
The output of this script is:
# ruby 2.5.0-dev on linux
vagrant@vagrant-ubuntu-trusty-64:/vagrant$ ruby -v

Raised error class is not mine point. This script with ruby 2.5.0-dev on linux returns false for server.closed?.
When any errors are raised, we should check whether it's raised by intentional sever.close or not. But it doesn't work well on ruby 2.5.0 on linux.
Is it possible to fix this problem?
Note: When I added some more p(here: "rescue", closed: server.closed?) lines in rescue clause, these (2nd and later) puts "true".
