Pharo no longer has a class 'StringHolder'. There considerable
discussion on the Pharo list about this. One issue was documentation

Doru the key difference with stringHolder is that in StringHolder
nobody understand how it works.
Because it I would know I would go way faster. So I suggest that we
spend next two weeks not typing code on moose but only fixing comments
and we will get a real impact.
For pharo I have always to reverse engineer (network, filesystem...)
because people forget that a soft is finihsed with it is really
documented.

This update is a very modest contribution to the documentation of
StringHolder  :-)

More input is welcome....
