* 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.
