- verify thread support (clone() and various locks)
- signals
- optimize translated cache chaining (DLL PLT-like system) - vm86 syscall support - overrides/16bit for string ops - more syscalls (in particular all 64 bit ones)
- make it self runnable (use same trick as ld.so : include its own relocator and libc)
- improved 16 bit support
- fix FPU exceptions (in particular: gen_op_fpush not before mem load)
