There are a few issues with the intel_s1000 runner:
- it doesn't attach to the client when running debug (this is
a part of the command's contract specified in core.py)
- it uses hard-coded sleeps when running subprocesses instead of
waiting for them to terminate
- it re-implements pre-existing popen_ignore_int() functionality (in a
way that is not portable to Windows) rather than using it directly
Fix these issues.
