And for those who would like to use it (or for Mac OS X users), a 
GitFileTree version using it is available by loading it this way:

Metacello new
         baseline: 'FileTree';
         repository: 'github://dalehenrich/filetree:issue_171/repository';
         load: 'Git'

> better end-user API. Also, as for the first step, I had to focus on
> Linux/OSX.

> There are many things on my to-do but I think the code is ready for some
> usage, testing, code review and feedback!
> All classes and all methods have comments and I have quite some unit
> tests. All tests are green in my OSX and a CentOS box.
> *Important: you CANNOT have OSProcess installed in the same image as
> OSSubprocess. This is because I am reusing his SIGCHLD handler and for
> the time being both cannot coexist. *
> Keep in mind that the tool may be unstable and that MAY mean a VM crash.
> So use with care, mostly the first time. If all tests passes, then there
> are much less chances of something going bad.
> Important disclaimer: my tool (OSSubproccess from now onward) is HIGHLY
> influenced by a subset of the OSProcess project. There are parts which I
> even simply copied and adapted them (OSSPipe, OSSAttachableStream,
> OSSUnixProcessExitStatus). Other parts, I took them as inspiration (the
> idea of ThisOSProcess representing the VM process, the child watcher,
> and many others). In addition, I AM STILL USING (maybe as a first step?)
> some of the OSProcess PLUGIN (not OSProcess image side), such as the
> SIGCHLD handler or the creation of pipes.
> In github url you have all the documentation of the project, included
> how to install it and use it.
> *Finally, if you test it in a OS different than OSX and CentOS please
> share with me the results (about the tests).* Tomorrow the
> ConfigurationOf should also appear in the Catalog of Pharo 5.0.
> Any feedback is appreciated.
> Best,
