We've a situation where we'd like to customise launch_parallel, and pass an extra argument to it in some cases.

The default is
launch_parallel = 'mpirun -np tc.nprocs'

but for various configs we'd like to have e.g.
launch_parallel='mpirun -np tc.nprocs --my-other-option'
or
launch_parallel='mpirun -np tc.nprocs --my-special-option'

Would it be possible to have a variable like
launch_parallel_template='mpirun -np tc.nprocs'
(which is a thing we might customise depending on the MPI implementation)

and then in the individual configs
launch_parallel='tc.launch_parallel_template --my-other-option'
or
launch_parallel='tc.launch_parallel_template --my-special-option'

I have the weird problem that the Quantum ESPRESSO testsuite (which uses testcode2 with --verbose) does not print out anything until the main testcode2.py program has finished, at which point the whole output is flushed.

This only happens when building Debian packages with sbuild, as is done on their (and Ubuntu's I believe) autobuilder network.

A solution is to add sys.stdout.flush() at the end of the for-loop in __init__.py:295:
