Here's the quote from [1]:
The master process is responsible for the following tasks:

- reading and validating configuration
- creating, binding and closing sockets
- starting, terminating and maintaining the configured number of worker processes
- reconfiguring without service interruption
- controlling non-stop binary upgrades (starting new binary and rolling back if necessary)
- re-opening log files
- compiling embedded Perl scripts

No, it couldn't be.
