I believe the following behavior is incorrect:

ruby -r timeout -e 'r = Ractor.new { Timeout.timeout(0.1) { sleep(1)       } rescue :timeout };             p r.take'
# => :timeout (ok)

ruby -r timeout -e 'r = Ractor.new { Timeout.timeout(0.1) { sleep(1)       } rescue :timeout }; sleep(0.2); p r.take'
# => :timeout (ok)

ruby -r timeout -e 'r = Ractor.new { Timeout.timeout(0.1) { Ractor.receive } rescue :timeout };             p r.take'
# => :timeout (ok)

ruby -r timeout -e 'r = Ractor.new { Timeout.timeout(0.1) { Ractor.receive } rescue :timeout }; sleep(0.2); p r.take'
<internal:ractor>:130:in `take': The outgoing-port is already closed (Ractor::ClosedError) # => not ok

I can confirm with it:

r = Ractor.new {
  begin
    pth = Thread.current
    Thread.new{ pth.kill }.join
  rescue => e
    p e
  end
}

p r.take
