Subject: 	* win/tclWinChan.c (FileCloseProc): Invoke 
 TclpCutFileChannel() to remove a FileInfo from 	the thread local list
 before deallocating it. 	This should have been done via an earlier 
 call to Tcl_CutChannel, but I was running into 	a crash in the next
 call to Tcl_CutChannel 	during the IO finalization stage.
