Portable System Utilities

Powerful replacements for base system2 with consistent behavior across platforms. Supports interruption, background tasks, and full control over 'STDOUT' / 'STDERR' binary or text streams. On Unix systems the package also has functions for evaluating expressions inside a temporary fork. Such evaluations have no side effects on the main R process, and support reliable interrupts and timeouts. This provides the basis for a 'sandboxing' mechanism.
