When using Build.Step.Run.captureStdOut with a program that prints more
than 10 megabytes of output, the build process hangs.
This is because evalGeneric returns an error without reading child's
stdin till the end, so we subsequently get stuck in `try child.wait()`.
To fix this, make sure to kill the child in case of an error!
