* 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.
