This is not a change I want to make, since as mentioned in that issue supporting musl is not something I plan to do.

I don't want to make large refactors to this code without a sufficient reason as it's an area that is quite brittle given how varied and unreliable linux can be in this regard. In my experience any code relying on the use of signals is a source of bugs as I've found them to be quite unreliable.

If you want to keep this code locally for use then you are free to do so, though I can't guarantee this will work in all situations or remain working in future.
