TypeError: setTimeout(...).unref is not a function

[mifi]

I use this module all the time including in Electron. After upgrading to the newest version i get this error when trying to call childprocess.kill() from an Electron application:

TypeError: setTimeout(...).unref is not a function
setKillTimeout
.../node_modules/execa/lib/kill.js:23:14

Note: with execa@1 it works. But 2 or 3 fails with this error. Maybe we could add a check for whether unref exists before calling it, or is Electron not supported anymore?
