[sr-dev] how to define an infinite while loop?

[Ovidiu Sas]

How about defining a new PV: '$true'.
If we have a constant word in the while loop, then yes, it might be a
missconfiguration and it is good to have the warning.
Having a '$true' PV will mean that we want an infinite loop and
there's no need to print the warning.
The '$true' will make the config more easy to read as opposed to
defining a variable just for the purpose of creating an infinite loop.

Thanks,
Ovidiu
