Found an issue and fixed it. Turns out destroying my #Process instance when the child exited was wrong, there could still be unread data in the #pipe. But then, only waiting for #EOF on the pipe was equally wrong ...
Now the code does the only reliable thing:
* When the child terminated, close the pipe for stdin immediately if one was present
* Only destroy the process instance once the child terminated AND the pipes for #stdout and #stderr (IF they were present) found EOF.

My testing code also had to change a bit and now makes for a completely pointless and cute wrapper around /bin/ls 馃檲 馃槀
