Yeah. Do we really think more precise timestamps are worth dropping
XP support? On the Unix side, I know exactly what would happen to a
patch proposing that we replace gettimeofday() with clock_gettime()
with no thought for backwards compatibility. Why would we expect
less on the Windows side?
Quite aside from XP ... AFAICS from the patch description, this patch
in itself moves us to a place that's a net negative in terms of
functionality. Maybe it's a stepping stone to something better,
but I think we should just go directly to the something better.
I don't care for committing regressions on the promise that they'll
get fixed later.
Or in short: let's do the work needed to adapt our code to what's
available on the particular Windows version *first*. Once we've
got that configuration support done, it shouldn't be much extra
work to continue XP support here.
