Sorry, my process table disagrees. Running 2.0.45, any command of the form:

Exec sub-command

versus

Exec exec sub-command

leaves a shell process wrapping sub-command, waiting to it to terminate. By
changing all my "Exec" instances to "Exec exec", I get an immediate savings
of 7 processes when I first login, before I really start to run applications.
