IO.new(9) doesn't work on linux

[bibstha]

Trying to get it running on ubuntu box and seems like IO.new(9) raises a bad file descriptor on linux. Works fine on Mac.

What does this do?

minidev/lib/dev/commands/cd.rb

Line 16 in 1f583ea

IO.new(9).puts("chdir:#{target}")

It's meant to connect to a file descriptor that we open from dev.sh for passing "finalizer" actions back to the shell script. I'm surprised it doesn't work on linux -- are you running it via the functions defined in dev.sh?
