Feature #14393: Support sending file descriptors (on local machine) via DRb UNIX

Currently DRb supports UNIX domain sockets, via drbunix://

UNIX sockets can transmit file descriptors via send_io()/recv_io() methods. Unfortunately DRb via drbunix:// doesn't support that yet. For instance when I try to do so on local machine, I get this error:

can't convert DRb::DRbObject to IO (DRb::DRbObject#to_io gives DRb::DRbObject) (TypeError)

Would you please consider adding support for sending file descriptors via DRb (of course on local machine)?

Thank you,

Would be nice.

I must admit that I have not used drb in a really long time - but I
am a firm believer in ruby objects dwelling everywhere, and communicating
with them. :)
