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.
