Retrieve context and save to thread context. NtQueryInformationThread is no longer required (right now?) because to retrieve the CONTEXT, the thread needs to be Suspend/ResumeThread'd anyway, and the return value of SuspendThread is the previous SuspendCount. I haven't handle the x86 case yet -- that would ideally be via Wow64GetThreadContext (I think) but unfortunately that's Vista+, so I'll likely need to to a bit of fiddling to get that sorted out. (It's actually likely going to be NtQueryInformationThread again, but one thing at a time for now.)
