commit 867630bb8fa7066172802243ca8abacb1e9aab6a
from: Stefan Sperling <stsp@stsp.name>
date: Fri Jan 17 11:54:27 2020 UTC

Sleep for one nanosecond after syncing the file index to disk

Ensures that files modified after got exits have a different timestamp
from the one which was recorded in the file index.
Previously, 'got status' did not always detect such files as modified.

Problem reported by Steven McDonald.
