Suggestion 1:

• home sends a ping every n seconds
• if worker has not received the ping after 5*n seconds, it commits suicide.

However... under heavy load this may be more damaging than helpful.

Suggestion 2:

• the home process conveys its PID to the worker at start
• the worker checks for a process with PID once in a while. If not found, it commits suicide

However, checking for a process in an OS-independent way is not very reliable either.
