[BUG] "redefining constant" warnings and Atom crash

[yha]

Since upgrading to Juno 0.12, I frequently see Atom crash when using Interact. There are "redefining constant" warnings on the first run cell, which I think didn't happen before.

Details

• Atom version: 1.44.0
• Julia version: 1.3.0
• OS: Windows 10
• Package versions:
  • Atom.jl: 0.12.3
  • julia-client: 0.12.0
  • ink: 0.12.0

Steps to reproduce

1. Evaluate a cell with

using Revise
using Interact

This gives the warnings

WARNING: redefining constant singleton_instance
WARNING: redefining constant routing_callback
WARNING: redefining constant webio_server_config

2. Kill Julia and evaluate again. Doing this repeatedly eventually crashes Atom.

I see those warnings too, but only if the Julia process isn't already running. I think that happens because Revise is triggered twice in that case.

Can't repro the Atom crash at all though.

I see the warning even if Julia is already running and I run the lines one by one. But I can't reproduce the crash anymore with the new julia-client version.
