There doesn't seem to be much advantage to this (we're already very diverged
from native i386 time handling) and the disadvantages are a bigger diff
versus what we need for x86/64 (hence more ifdefs) and independent_wallclock
probably stops working.

This is all solvable I'm sure, particularly if clocksources are the way of
the future (e.g., is x86/64 native going to use generic_time any time soon)?
