tests: de-flake test-narrow-share.t by making dirstate predictable
test-narrow-share.t was sometimes (~0.5% on my machine) failing like this:
@@ -61,7 +61,7 @@ A d3/g $ hg -R main debugdirstate --no-dates n 644 2 set d1/f - n 644 2 unset d3/f + n 644 2 set d3/f a 0 -1 unset d3/g n 644 2 set d5/f n 644 2 set d7/f
The timestamp for d3/f would get set if it was determined at some
point that it was clean. That check is usually done when the user runs
hg st. We don't do that before the failure in the test case, but it
happens at the end of the hg clone call. So if the file system's
time happens to roll over after the clone's working copy has been
written, but before its (final) dirstate has been written, we can end
up with a set timestamp there.
This patch makes it consistent by sleeping for 2 seconds so the
timestamp gets reliably set.
