module Util
# This module provies a `safe_exec` method which is a drop-in
# replacement for `Kernel.exec` which addresses a specific issue
# which manifests on OS X 10.5 and perhaps other operating systems.
# This issue causes `exec` to fail if there is more than one system
# thread. In that case, `safe_exec` automatically falls back to
# forking.
