Huh ... I'd forgotten about that ... although it seems to work only for
rather small values of "work", since the WIN32 code path isn't paying
attention to the "who" argument.

Yeah, the real bottom line here is whether we are buying anything that's
worth another two kernel calls per function.  Given all the buffering
and offloading of I/O to bgwriter that we try to do, it's hard to argue
that stime/utime measurements for the current backend really mean a lot.
