The manager approach is a viable solution, but I believe it has the additional hassles of:

writing a separate manager module

starting and stopping the separate manager module when the program runs/stops

detecting failures: as the manager is one more component in your system, what happens if it goes wrong? what happens if it segfaults? what happens if it does not work properly?

Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
