* generic/tclIORChan.c (ReflectClose): Added missing removal of
the now closed channel from the reflection map. Before we could crash the system by invoking 'chan postevent' on a closed reflected channel, dereferencing the dangling pointer in the map. * tests/ioCmd.test (iocmd-31.8): Testcase for the above.
