@jcheng5, reported:

BTW I think you need to move the pid out of the cached value, otherwise multicore-backed futures will have the same session_uuid as their parent.

> library(future)
> plan(multicore)
> future:::session_uuid()
[1] "2036af94-e369-5dc9-4948-62e0fb2336a6"
> value(future(future:::session_uuid()))
[1] "2036af94-e369-5dc9-4948-62e0fb2336a6"

Action

  1. Add unit tests for this.
  2. Fix it.
