Yes it will. What's pinned down is a call to a constructor (with a  
pinned value,
but there is a fixed and finite number of such values), so that every  
time
that code executes, a new String is created, and that will get GC'd.  
Symbols
avoid the overhead of constructing and GC'ing new Strings, but the  
problem
Cezary is talking about is where code that creates Symbols dynamically  
from
Strings, that can create a potentially unbounded number of Symbols,  
none of
which can be GC'd.
