Comment (by waddlesplash):

We can still do a reasonably accurate progress bar: it would progress to

50% after doing all the copies, and then to 100% after doing all the Sync,
for example

But then on most systems the progress bar will just lock at 50% for a long
time and jump to 100% immediately, or it will jump from 50 to 100 without
any delay. Neither is a good idea.

The only different way to solve this problem that seems acceptable to me
would be doing write+sync in one stage in one thread, with reads in a
separate thread. But in my experience, again, reads are so much faster
than writes that the architectural modifications to support this are
likely not worth making.
