For example, I see  file-system stuff in Host, process launching stuff, and more.  I'm currently thinking about maybe separating the stuff in Host into different logical groups, and then moving that functionality into their own Host-layer classes.  So we'd have lldb_host::FileSystem, for example, which would contain the Readlink, Unlink, etc functions.  And an lldb_host::ProcessLauncher interface, which would support different ways of launching processes, with derived implementations such as PosixSpawnProcessLauncher, ExecProcessLauncher, ForkProcessLauncher, WindowsProcessLauncher, etc etc.  Then existing code that launches processes could use these classes instead.

All possible, and any cleanup is good. Feel free to use your time as you see fit! We don't mind benefitting from your work.
