[Message part 1 (text/plain, inline)]

I added the set-process-filter in case that would make a difference, but I
don't think that is the issue here. The issue is that the services (sub
processes of Emacs as you say) takes a long time to respond when Emacs is
idle. If I run the same command from a terminal, that doesn't happen.
