# The tempfile library as included in Ruby 1.9.1-p152 and later
# contains a bug: unlinking an open Tempfile object also closes
# it, which breaks our expected POSIX semantics. This problem
# has been fixed in Ruby 1.9.2, but the Ruby team chose not to
# include the bug fix in later versions of the 1.9.1 series.
