That's what exec *is*. `man exec` (for the C function Perl calls) yields:
DESCRIPTION
The exec family of functions replaces the current process
image with a new process image.
`perldoc -f exec` says:
The C<exec()> function executes a system command I<AND NEVER RETURNS>
If you want a program that repeatedly exec's while continuing to run in the
background, you need to have it fork() off a child each time it want to do
this, and exec() in the child.
