We weren't closing the streams after we were done reading or writing, which is kind of essential. The easy way to fix this is to just use g_output_stream_splice() to a GMemoryOutputStream rather than hand-rolling it. This results in a substantial reduction of code complexity. A second serious issue is that we were marking the task as complete when the process exits, but that's racy - there could still be data to read from stdout. Fix this by just refcounting outstanding operations. This code, not surprisingly, looks a lot like the "multi" test. Next, because processes output binary data, I'd be forced to annotate the char*/length pairs as (array) (element-type uint8). But rather than doing that, it's *far* simpler to just use GBytes. We need a version of this that actually validates as UTF-8, that will be in the next patch.
