The main reasons are:

- The code still has to work after Chromium has moved it to a different memory location.
  A relative jump would not be suitable for that. Also, in our proof of concept patch,
  we want to avoid huge syscall tables, and instead pass a pointer in %eax.
- DRM applications might complain when a function entry point looks too unusual.
- In "non-relaxed" mode Chromium refuses to accept the entry point, if it doesn't match
  exactly the function signature on Windows. I don't think this is used for Steam yet,
  but its just a matter of time.
