When I type C-x C-f xmail/foox TAB, where xmail contains 800 files
and none of them starts with foox, it takes a few seconds (including
3 GCs) before telling me it can't be found.
Here's output from xbacktrace:
"file-name-completion" (0x7fbe23e4)

I think that is because of the partial completion feature
that is now enabled by default and was not before.
I don't notice (or mind) the feature itself. But the delay
is a real pain whenever I make a typo in these names.
I think the feature should be disabled by default
if it can't be made fast enough to run in half a second.
This is on the Lemote Yeelong mini-laptop.
