Using exit (or quit) hangs jdb in Windows 95 (but apparently not in
Solaris or Windows NT). The following cases were tried. First, a simple:

    > jdb
        Initializing jdb ...
    > quit
        [hangs; killed after 15+ seconds with ctrl-C]

Second, in demo\\Fractal:

    > appletviewer -debug example1.html
        Initializing jdb
        0x139f198:class(sun.applet.AppletViewer)
    > run
        ...
        Uncaught exception: java.lang.NumberFormatException null
at java.lang.Integer.parseInt(Integer.java:126)
...
    thread applet-CLSFractal.class[1] quit
        [hangs]

Tried the same appletviewer -debug example1.html on Kevin's NT machine
and it worked fine. Also, the applet works on Win95 if the appletviewer is run
without the -debug switch.
