Is there any way to measure the amount of data getting sent to workers? For the example in the [Data Movement section of the Distributed Manual](https://docs.julialang.org/en/v1/manual/distributed-computing/#Data-Movement), it would be very helpful to tell if a call is moving data or not, to directly compare, especially when data movement can be both implicit and explicit.

I have a case where [two processes have a variable theta](https://github.com/FluxML/Flux.jl/issues/2102), but theta is still getting moved to the worker, instead of the worker using the theta native to the process.
