Feature or enhancement

Proposal:

In #122525, it was observed that many functions of the platform module use cached results. This is, in practice, preferrable, but it should also be possible, if needed, to invalidate cached results. One use case is when the host name changes (i.e., one of the uname() components change).

Has this already been discussed elsewhere?

   Mostly out of curiosity - is there any way to watch for host name change?

   Well.. you could have a task that runs every second and checks whether the host name changed or not. socket.gethostname gives you the runtime one, so you'll need to query it every second.
