TODO

   1 - fix gcc 2.96 compile bug
   2 - fix thread locks
   3 - optimize translated cache chaining (DLL PLT-like system)
   4 - fix thread stack freeing (use kernel 2.5.x CLONE_CHILD_CLEARTID)
   5 - fix x86 stack allocation
   6 - fix iret/lret restarting
   7 - more syscalls (in particular all 64 bit ones, IPCs, fix 64 bit
   8   issues, fix 16 bit uid issues)
   9 - finish signal handing (fp87 state, more siginfo conversions)
  10 - fix FPU exceptions (in particular: gen_op_fpush not before mem load)
  11 - handle self-modifying code (track mmap and mark all pages containing
  12   translated code as readonly. use a custom signal handler to flush
  13   parts of the translation cache if write access to a readonly page
  14   containing translated code).
  15 - use gcc to compile to static code
