Time to commit remote ops for VirtualAllocEx, CreateRemoteThread

[Dan Kegel]

Tommy's APC version of his
VirtualAllocEx / CreateRemoteThread patch
seems to be safe (since APCs only run a points where threads
in well-written programs are not holding locks),
is complete enough to make many apps happy,
and is probably the best that can be done without
a service thread or a real kernel change.
I've encouraged him to submit it for real.
Let's get this puppy committed!
