Bugfix: Replace TVar with TMVar for the old value
This solves a problem when there is only one pipe in place. With a default value of "" and only one pipe with a timeout the value is overwritten with "" after the timeout. To prevent this from happening a TMVar is used which will never be filled if there is only one pipe.
