AFAIK, the only place where it is used in the JDK is in j.u.zip.ZipFile 
where a zip file can be opened with a mode that includes 
ZipFile.OPEN_DELETE. It might be tricky to get that dependency removed 
in a timely manner from both jdk6 and jdk7. It might be good to include 
a comment as it's clearly a curiosity.  As regards Windows, I believe 
this is defined as O_TEMPORARY in jvm.h, which in turned is probably 
mapped by the Microsoft C runtime to the DELETE_ON_CLOSE flag (so no 
equivalent to the unlink required).
