Can't send signals using signal numbers

Using process.kill with signal numbers should work according to the documentation, but I get an ERR_UNKNOWN_SIGNAL error when using numbers instead of strings. For example:

$ node
> process.kill(process.pid, "SIGTERM")
Terminated

$ node
> 15 === require("constants").SIGTERM
true
> process.kill(process.pid, 15)
TypeError [ERR_UNKNOWN_SIGNAL]: Unknown signal: 15
    at process.kill (internal/process.js:168:15)

Looks like a doc issue (ambiguity). Supported are signal names

Signal names are strings such as 'SIGINT' or 'SIGHUP'. See Signal Events and kill(2) for more information.

and 0:

As a special case, a signal of 0 can be used to test for the existence of a process.

Or is this a featue request to support signal numbers there?

Oh, you are right. I didn't read the documentation carefully enough. Sorry :/

There's an open pull request for it, #16944, but it's blocked on failing tests.
