How does distribute clean up Distributed without shutting down parallel processes  
Because it takes time to start the loop, and obviously the second run is faster than the first, I cycle through the parallel process and don’t want to quit and start the parallel process again.  
First, the process 3 variable is called in the first loop

```julia
remotecall_fetch(varinfo, 3)
   name size summary
   ––––––––––––––––––––––––––––
   Base Module
   Core Module
   Distributed 1.454 GiB Module
   Main Module
The second loop calls process 3 variables
remotecall_fetch(varinfo, 5)
   name size summary
––––––––––––––––––––––––––––––––––––––––––––––
   Base Module
   Core Module
   Distributed 2.907 GiB Module
   Main Module
   drr3d_atuo 0 bytes drr3d_atuo (generic function with 1 method)

```

Use

```julia
clear! (:Distributed) 

```

will cause an error, prompting  
**invalid redefinition of constant Distributed!**
