Few more emulator fixes. Each is logically independent from the others. The first one is the most interesting one. It appears that the current behavior may cause the VM to enter the page-fault handler twice on certain faulting write accesses. If you do not like my solution, please propose a better one. The fourth (JMP/CALL using call- or task-gate) is not a fix, but returns an error instead of emulating the wrong (#GP) exception. Thanks for reviewing the patches.
