I created a related topic here - as this doesn’t seem related to `HTTP.jl` package:

It turned out that the issue was unrelated to the HTTP.jl package and went deeper. Now, the experiment (with nthreads() \> 2). Important note: to avoid “what if” scenarios about the resource allocation to the running tasks when using 1-2 threads, I suggest running this with -t 3 or above. Also, for this MWE it doesn’t make any difference if the tasks are spawned on :interactiv…
