Class cornell.slk.jkernel.core.SystemRuntimeSafe

Source code
java.lang.Object
    |
    +----cornell.slk.jkernel.core.SystemRuntimeSafe
public final class SystemRuntimeSafe
extends java.lang.Object
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.
