Xapian itself has Tcl bindings, and they also silently fail to lock the file. So does putting a minimally changed copy of Xapian's locking code directly in a Tcl extension, though that code works when called from a tiny C main program instead. So thanks for looking, I will report here if I find out why. Eric -- ms fnd in a lbry
