# This script will mount /Users in the boot2docker VM using NFS (instead of the
# default vboxsf). It's probably not a good idea to run it while there are
# Docker containers running in boot2docker.

# Usage: sudo ./boot2docker-use-nfs.sh

# Trying to grasp fibers and EM!
# Using this example: http://www.slideshare.net/kbal11/ruby-19-fibers (slide 54)

# Fiber#resume(*params) => when first called, it passes all params as block params to
# Fiber.new
# In the next calls of resumes, *params is the return value of any Fiber.yield

# Fiber.yield stops execution of current fiber

# So, in the run-loop from EM, the fiber stops execution and gives up control
