The Java Virtual Machine (JVM) can be decoupled from its Java-enabled browser.
To maintain access to certain system resources (a "privilege") by applets, each
Java thread that enables the privilege will now create an entry that describes
the privilege in a linked list based on the stack frame address. Sufficient information
is stored in the link list for validation purposes. Further, system classes that
require specific privileges will have them implicitly granted by an implicit privilege list.
