Here is before and after of this PR that I observe, and I see these 2
changes
- now it does not stream output, i.e. it waits for the entire paragraph
execution to be finished, and returns result.
- and I see empty line between "1" and "2" where I wrote "Thread.sleep()",
not a big deal, but it wasn't earlier.
