# As of Python 3.12, debugpy runs a forwarding process that listens both on the port specified here for the debugger
# to connect to, but also on an internal port for the underlying pydevd within the python process to connect to.  The
# default for that internal port is 5678, so we need to not duplicate it for the external port.  Also, on Linux the
# attempt to spawn the forwarding process separately fails, so we force it to be internal to our main process.
