select [or in 1.9 fibers].

You'd have to have some socket within it that will interrupt.

like interruptor = TCPSocket.new( '', 3333)

 select [interruptor], nil, nil

then in other thread
a TCPSocket.new('localhost', 3333)
# to interrupt
a.send 'a'

something like that

Or if you didn't care about thread safety you could use Thread.raise 
[scary].

But overall I might suggest eventmachine or revactor for what you want.
Cheers!
