Description

I realized some problems with DRb and BasicObject

  1. I cannot create front object of BasicObject class because DRb tries to call private_methods class

  2. Call to DRb can't return instance of BasicObject class, instead it hangs.

serv.rb:

require 'drb'
$drb_uri = 'druby://localhost:1111'
class Front
def func
BasicObject.new
end
end
DRb.start_service($drb_uri, Front.new)
DRb.thread.join

conn.rb:

require 'drb'
$drb_uri = 'druby://localhost:1111'
DRb.start_service
conn = DRbObject.new_with_uri($drb_uri)
p conn.func

When after a while (tens of seconds) I break the server, client shows me trace:

conn.rb
