In this case it isn't in the kernel, but in glibc. Could someone implement an equivalent alternative? Do any language runtimes re-implement DNS resolution?

  I think most languages use the OS api by default, but there are plenty of libraries out there that bypass the system resolution.

  Go does. And it supports timeouts and cancelation.
