+ * for a discussion of how Beast launches a browser, a link that shows
+ * the rather complicated code it uses, and some information on why it
+ * goes through all that pain. See also Kevin Krammer's comment, which
+ * notes that the problem might be that the GNOME, KDE, and XFCE
+ * launcher programs always cause the window to be opened in the background,
+ * regardless of whether an instance of the app is running or not (the
+ * app gets launched - in the background - if it's not already running,
+ * and is told to open a new window/tab if it's already running), while
+ * launchers such as sensible-browser, which xdg-open falls back to,
+ * launch the app in the foreground if it's not already running, leading
+ * to the "first window is in the foreground, subsequent windows are in
+ * the background" behavior in non-GNOME/KDE/XFCE environments.
+ *
+ * Perhaps the right strategy is to:
+ *
+ * Check whether we're in a GNOME/KDE/XFCE session and, if
+ * we are, try xdg-open, as it works around, among other things,
+ * some kfmclient bugs, and run it synchronously (that will fail
+ * if we detect a GNOME/KDE/XFCE session but the launcher is
+ * missing, but so it goes). If we don't have xdg-open, try
+ * the appropriate launcher for the environment, but ignore
+ * the return code from kfmclient, as it might be bogus (that's
+ * the bug xdg-open works around).
+ *
+ * Otherwise, try the "broken/unpredictable browser launchers",
+ * but run them in the background and leave them running, and
+ * ignore the exit code, and then try x-www-browser, and then
+ * try directly launching a user-specified browser. (Beast tries
+ * a bunch of browsers, with the user not being allowed to
+ * specify which one they want.)
+ *
+ * On the other hand, see bug 2699, in which xdg-open is itself buggy.
