Review comment:
Why ?!
This is a huge side effect here.
Calling `getStatus()` should not unset such important state.
Also I think `getFunctionsExecuterStatus` should not be public, i.e. it
should not be possible for the application code to be able to execute it at
all. It shouldn't be a member of `Call`
