Windows has an API for reducing the priority of I/O and memory usage,
namely SetPriorityClass():
https://msdn.microsoft.com/en-us/library/windows/desktop/ms686219(v=vs.85).aspx
with the PROCESS_MODE_BACKGROUND_BEGIN**arg.
However - inexplicably - this arg can be used only by a process on itself, not
another process.
So we could call this from boinc_init() on Win, but it wouldn't work with
existing apps.

The main question here is: Is there a way to prioritize Memory and I/O access? If
yes is it available on all platforms (Windows, Mac, Linux)? If not, is there a
general way to get the load information from and schedule accordingly?
You would still have to distinguish between BOINC generated Memory and I/O
operations and from other apps. This seems very tricky.
