Review Comment:
This seems to be incorrect as closing here is wrong as a general rule as the
resource that opened this should be closing it but also this is occurring in a
different thread than the connection thread where the reader was opened which
could lead to error on inconsistent state. The receiver should be closing this
in the connection thread.
