lineage-driven fault injection

since all IO and cross-thread communication points are manually instrumented with failpoints and debug_delay, we can use these calls to record traces of IO and linearization points. * run a...

I believe the way to go about this is through https://retep998.github.io/doc/kernel32/fn.WriteFile.html and passing in an [OVERLAPPED](https://retep998.github.io/doc/winapi/minwinbase/struct.OVERLAPPED.html) struct, as per [SO](https://stackoverflow.com/questions/3852758/equivalent-to-pread-pwrite-in-msvc)....
