Nice.

Changing "yield inprogress.result" to "result = inprogress.result" does
the trick, so now this is shown:
./freevo --execute=src/tv/record_client.py pingco
function='pingco' args=[]
0.000: pingCo started
0.003: pingCo.inprogress=<kaa.async.InProgress object at 0xb68bf74c>
0.013: pingCo.inprogress=<kaa.async.InProgress object at 0xb68bf74c>
0.015: pingCo finished=True
0.019: pingCo=None
This not quite correct as I would like the result of the pingCo to be
obtained. How do we do this now?

This is correct findNextProgram is not called. What is the correct way
to call this; Doing the same as with pingWait does work but may not be
the best method?

This one does write the debug message to the log, changing this to a
print shows:
# ./freevo --execute=src/tv/record_client.py pingnow
function='pingnow' args=[]
pingNow.result=True
0.014: result=True
Thanks for this
