From: Tao Klerks <tao@xxxxxxxxxx>
The untracked cache test uses an avoid_racy function to deal with
an mtime-resolution challenge in testing: If an untracked cache
entry's mtime falls in the same second as the mtime of the index
the untracked cache was stored in, then it cannot be trusted.
Explicitly delaying tests is a simple effective strategy to
avoid these issues, but should be avoided where possible.
Switch from a delay-based strategy to instead backdating
all file changes using test-tool chmtime, where that is an
option, to shave 9 seconds off the test run time.
Don't update test cases that delay for other reasons, for now at
least (4 seconds).
