"""
The aim of this configuration is to run a local htex
in a similar manner to htex_local.py, but with lots of
options different and more complicated than in that
configuration, so that more code paths are executed
than when testing only with htex_local.

It does not matter too much *what* is different in this
configuration; what matters is that the differences
cause significantly different pieces of parsl code to be
run - for example, by turning on monitoring, by allowing
blocks to be started by a strategy, by using a different
set of staging providers, by using timing parameters that
will cause substantially different behaviour on whatever
those timing parameters control.
