Opsss, and more extrange:
Note the following:

irb> drb_client.current_threads
=> #<DRb::DRbObject:0xb7b8d384 @ref=-608642478, @uri="druby://0.0.0.0:10001">

irb> puts drb_client.current_threads
#<Thread:0xb7c8f700>
#<Thread:0xb76f9598>
#<Thread:0xb76f9a98>
#<Thread:0xb76f9890>
#<Thread:0xb76f91b0>
=> nil

How is it possible? why "puts" gets this?


irb> puts drb_client.current_threads.class
DRb::DRbObject
=> nil
