And the answer is...it depends.  OS X doesn't have /proc, so (1) Mono
itself will run w/o /proc, but...  (2) some parts of the class library
will NOT work.  For example, Process.GetProcesses() will generate a
NullReferenceException, because EnumProcesses() requires /proc (see
mono/io-layer/processes.c).

So it depends entirely on which parts of the class library you're using.
