Hit the following while running go-fuse tests in a loop:

$ time while true; do echo; go test -p 1 -count 1 ./... || break ; done
--- FAIL: TestLargeDirRead (0.01s)
    loopback_test.go:686: readdir mismatch got 99 wanted 100
FAIL
FAIL    github.com/hanwen/go-fuse/fuse/test     1.824s
...
FAIL

real    0m31,778s
user    0m20,065s
sys     0m15,040s

Retrying only that particular test fails reliably in around 5-100 seconds, e.g.:

(neo) (z-dev) (g.env) kirr@deca:~/src/neo/src/github.com/hanwen/go-fuse/fuse/test$ time while true; do echo; go test -run TestLargeDirRead -p 1 -count 1 ./... || break ; done

I can repro here on Fedora 38. Took 2 minutes of looping.
