It turns out this isn't a GC issue. After starting the `WebService` once,
if I terminate it from the Process Browser and restart it, it won't work
correctly again.  I have to restart the VM and then start the `WebServer`..
Not sure why. Perhaps terminating the "Webserver's listening process" from
the Process Browser after making code changes in my server code is not the
right approach.
