Tools/Scripts/webkitpy/common/system/systemhost.py:47: def print_(self, *args,
**kwargs):
Adding this wrapper allows us to capture stdout and stderr output w/o needing
the full hoop-jumping of outputcapture (and needing to step on and restore
sys.stdout and sys.stderr).

Also, if we change code to call host.print_() rather than "print", this gives us
a simpler migration path to Python3 (where print becomes a function, not a
statement).

Unfortunately "print" is a reserved word and so we can't call the method
"print". Using "print_" follows the convention in the popular 2to3 wrapper
library, 6.
