+	* lib/tempfile.rb (Tempfile#unlink, Tempfile::Remover#call): Just
+	  call File.unlink and ignore ENOENT because existence check
+	  before unlinking does not help in terms of race condition.
+
+	* lib/tempfile.rb (Tempfile#unlink, Tempfile::Remover#call): My
+	  comment about thread safeness is obsolete.
