It's a very good question and, yes, as far as I know, it is single threaded.
However, testing demonstrates a direct correlation between service and exec statements and examining the code indicates that they use the same routines to call out to the shell. Also, I found that the translation of a brain dead simple exec could, in most cases, change it from a >=1s runtime to a <=0.01s runtime. Why this happens.....I'll let the PL guys answer....because I stopped going down that rabbit hole when I figured out how. The bad news is that services are just slow on the base OS so no help there if you're managing a lot of them.
