arya/bluepill — Issue #139: Processes are continuously restarted
Author: ndwns
Created: 2012-02-22 00:38:14+00:00
State: open

`Bluepill::Process#signal_process` is used with a numeric code when determining if the process is running.
The change in dd29b02903 breaks that usage as 'SIG0' is not a valid name.

```
Process.kill(0.to_s.upcase, $$)
> ArgumentError: unsupported name `SIG0'
