times you'd end up losing clients (thinking they had gone away). From the ICCCM (which should not be read without a stiff drink in hand, I made this mistake so you don't have to): to request a window to be withdrawn one should send a synthetic UnmapRequest event when iconified. To request iconification one should just unmap the window. The ICCM further recommends that the synthetic event should just be taken as a cue to withdraw, to deal with legacy clients. Taking a hint from this, rework xev_handle_unmaprequest to correctly detect these situations. A Withdrawn window may come back anywhere, even as a subwindow of something else, so the correct way to handle this state is to forget it ever existed. While i'm here, kill a dumb attempt to notice this in client_delete, and nuke the very unnecessary arguments. Todd confirmed this fixes the `race'. ok todd@, ok ok okan@
