Thank you Jacques!
I looked at semaphore-wait-seconds & semaphore-sleep there is no documentation
in the schema, how the whole thing works?

Simply use the semaphore attribute of the service, with value wait

Say, a user registers on my site, through a form; I am running a service
that does the registration.
Now suppose 10 users use the form simultaneously and submit their
registration at approximately the same time. My service is called 10 times.
I want to guarantee that one and ONLY ONE instance of my
registration service runs at any given time.
I need that because in my specific scenario each subsequent registration
depends on the previous ones.
Can I make my service asynchronous and use the job scheduler to achieve my
goal?
Thanks in advance ;)
