Feat: now execs instead of exec + fork if going to exit.

One quick solution to the lack of tracking deep into the command line is
to note that the pattern of code emitted for an async is:

Xasync
|__ child  (command)
|__ parent (continues)

The child creates a process group, as described before. If the child is
a simple command, we will now "exec" as it will exit immediately after
the command. This gives us the correct behavior, at least for simple
cases.

This also fixed pipes. However, if child has to be forked, i.e. can't be
immediately execed, then I don't think this process works...
