[bug#45018] [PATCH 0/6] Process and connection reuse for substitutions

[Mathieu Othacehe]

Hey Ludo,

> Blue are periods where the process is running, and grey where it’s
> idle—e.g., waiting for data.  After each substitution completion,

That's a great improvement! Besides a few remarks, it looks good to me!

Thanks,

Mathieu
