Class cornell.slk.jkernel.core.SystemRuntimeDangerous

Source code
java.lang.Object
    |
    +----cornell.slk.jkernel.core.SystemRuntimeDangerous
public class SystemRuntimeDangerous
extends java.lang.Object
implements SystemRuntimeDangerousInterface
Runtime and System are a hodgepodge of harmless and extremely dangerous functions all mixed together. Language functions (arrayCopy, identityHashCode) are mixed freely with system functions (exec, currentTimeMillis).

SystemRuntimeSafe extracts the harmless things, while SystemRuntimeDangerous extracts the dangerous ones. SystemRuntimeSafe is placed in the standard resolver, while SystemRuntimeDangerous is not.

Later we should probably take all the system functions (as opposed to the language functions), and export these through capabilities.
