We might not have sufficient privileges to signal the child process
so don't make assumptions about the return value of `uv_process_kill()`.
Example:
node -e 'child_process.spawnSync("sudo", ["ls"], { maxBuffer: 1 })'
No test because:
1. The test needs to run as root (can't invoke sudo), and
2. The parent needs to drop privileges but can't, because
then the child process won't have sufficient privileges.
