Implementation

• Boehm conservative GC; only stack scanned conservatively; somewhat possible to plug in a new GC
• Small base porting layer: threads, I/O, Process
  Runs on ARM, MIPS, x86, Alpha, PPC, S/390, Sparc, IA-64, SH, x86-64
  Runs on Linux, other Unix, Windows, newlib
  
• All core native code written in C++
• Standard library precompiled to a .so
• Built-in interpreter
  Interpreter requires extra porting of libffi
