If you look at it in the documentation, though, there is a discussion of
exactly this, pointing out that the Director needs an additional
connection to get status from any daemon, and that you should always
allow for a couple of "spare" connections in case needed.

Perhaps the directive might be better named "maximum connections", as
that's what it's really limiting, not jobs; but then it'd still be
necessary to explain that each job to run concurrently requires a
connection plus the director needs at least one additional connection
for status and control.  I don't believe there is any mechanism at the
moment to prevent you from - intentionally or accidentally - starting
sufficient simultaneous jobs on a client to consume all available
connections.
