4Subject: [PATCH 1/3] utils: Ensure stdout/stderr are flushed
5
6There is no guarantee that the data written with fwrite will be flushed to the
7buffer. If stdout and stderr are the same thing, this could lead to interleaved
8writes. The common case is stdout output so flush the output pipes when writing to
9stderr. Also flush stdout before the function returns.

4Subject: [PATCH 2/3] use process groups when spawning
5
6Rather than just killing the process we've swawned, set the process group
7for spawned children and then kill the group of processes.

4Subject: [PATCH 3/3] utils: Ensure pipes are read after exit
5
6There was a race in the code where the pipes may not be read after the process has exited
7and data may be left behind in them. This change to ordering ensures the pipes are read
8after the exit code has been read meaning no data can be left behind and the logs should
9be complete.
