Before this fix there were various issues with the test server
framework, most noticeably servers stopping when they shouldn't
causing timeouts. This was caused by the reference counting in the Go
code not being engineered to work in multiple processes so it was not
working at all properly.
This fix moves the reference counting logic to the start scripts and
in turn removes that logic from the Go code. This means that the
reference counting is now global and works correctly over multiple
processes.
