/* XXX: Warning:
        Note that capture_interface_list() is called directly (or indirectly) during the
         creation of (and changes to) the capture options dialog window.

        Also note that capture_interface_list() indirectly runs the gtk main loop temporarily
         to process queued events (which may include button-presses, key-presses, etc).
         (This is done while awaiting a response from dumpcap which is invoked to obtain
          the capture interface list).
        This means other Wireshark callbacks can be invoked while the capture options window
         is being created or updated (in effect an "interrupt" can occur).

        Needless to say, "race conditions" may occur in "interrupt" code which depends upon the exact
        state of the capture options dialog window and which may be invoked during the
        creation of (or changes to) the capture options dialog window.

        For example: if a user hits "Capture:Options" and then immediately hits "Capture:Start",
         capture_start_cb() may be invoked before capture_prep_cb() has been completed (i.e., during
         a call to capture_interface_list() in the code which creates the capture options window).
        capture_start_cb() depends upon certain properties of the capture options window having been
         initialized and thus fails if the properties have not (yet) been initialized.

        An interlock has been added to handle this particular situation;
        Ideally a more general solution should be implemented since it's probably difficult
         (if not nearly impossible) to identify all the possible "race conditions".

        ? Prevent the temporary running of the gtk main loop in cases wherein dumpcap is invoked for a
          simple request/reply ? (e.g., capture_interface_list()) ??

        ? Other ??
