So presumably you just need to make vex-x86 treat that as a syscall
instruction and end the BB so valgrind gets control and then Naveen
can worry about writing a system call handler to haul values out of
the appropriate registers.

In principle we could use that on linux as well and remove the hack
that forces int $80 for system calls.
