Could continue fetching after a virtualized instruction is found.

intra-page static branchs can be direct.

add __attribute__ ((format...)) to printf like functions

After another tcode chunk is added to the linked list, the remaining
  space is not used.

Invalidate all dt stuff after hashID rolls over.

Fix pushF stuff in tcode/stubs.

ID check value is init'd to 0.  Is this OK?

For DT tcode generation, rather than negate original conditional
  branches, could use original condition and branch to separate
  tcode sequence for branch case.  Following tcode models following
  guest code.  Retains original branch order, and eliminates a
  branch when not taken.

Are mods to stack variables optimized out at end of function?
  This would be bad for asm/C handler code.

Need user options for controlling VM and DT behaviours.  And
  better options processing (maybe a single ioctl).

Zeroing of monitor/DT structures.  Are we zeroing these
  upon startup?  Maybe the host_alloc/host_alloc_page should
  be required to zero these.  Or do it in init_monitor().
  Some things are done in dt/

RM<->PM switching: do I take into account CR0 bits for
  Page Meta Info?  Do I need to?

Search for xxx

Take care of copyright year diffs.

What about CS.limit and prescanning?  Do we test
  this before scanning?

Could manage CS/EIP virtualization better.  Fix only
  just before use, like in emulate() etc.

Need to deal with permissions for tcode pages,
  boundary checks for monitor address in those pages
  since the guest can modify them.

Deal with handling of TF for native use vs RunGuestNMethodBreakpoint?

Synchronization of global ID patched into branch tcode
  (currently in r3h_branch).

Expand L2M --> LPAToMI

Backpatching conditionally in C function, depending on
  which asm shim calls it.

Must increment globalID every context switch (anything that could
  make us recompare the criteria in the meta entries).

Need an ioctl mechanism to set all VM options at one time, including
  the SIV=0 ones like runRMAsVM86, runVM86Native, runPMR3Native.
