Null and Garbage Collection

 Obviously, if you null a reference it becomes a candidate for GC
sooner. In ordinary Java code, it is most common that you would exit
the method almost immediately after such a nulling, so it buys you
nothing for local variables allocated during the method invocation. 

 However, if you had some very complicated method, it could pay to
null half-way through execution. But that being true is a symptom that
you probably would want to refactor the routine in two, which would
then most likely obviate the nulling.

Why do so many operating systems refuse to define a standard 
temporary file marking mechanism? It could be a reserved lead character
such as the ~ or a reserved extension such as .tmp.
It could be a file attribute bit. Because they refuse, there is no 
fool-proof way to scan a disk for orphaned temporary files and delete them. 
Further, you can't tell where the orhaned files ame from. 
This means the hard disks gradually fill up with garbage.
