The following are examples of running rb_objcpu.d.
The rb_objnew.d script reports the on-CPU time for new Object creation in Ruby
while the script is tracing. Here we see it running while
Code/Ruby/func_abc.rb is executed.

We can see that there were several different types of Objects created
including three of type 'Object', one of which took 1 microsecond, one of
which took 2 to 3 microseconds, and the last of which took between 8 and 15
microseconds.
