Hi,

quoting upstream
(https://raw.githubusercontent.com/jirka-h/haveged/7ae444b7a0aa64a96729d78dd724b4398b9b0eaa/README.md)
```
The --enable-threads option is an experimental prototype for running
multiple
collection threads in a single haveged instance. The goal is to create a
multi-core haveged that would spread collection overhead more evenly
over the
available cpu resources.
```

I assume you read it as well and and I agree this option should be
disabled by default due to its experimental character (or at best made
configurable).

Regards
