Description

sanity 171 in master could, and actually did for me, fail because of a race between the bash process executing test_171() and the background multiop process. By the time when test_171() returns, the multiop process could still be asleep. Test Framework would complain in run_one() about the existence of the multiop process, failing the subtest.

Another issue with this subtest is that the usage of multiop_bg_pause() is a little tricky. Since the subtest does specify any "_" for multiop, no "PAUSING" will be printed. As a result, the multiop_bg_pause() always fail after the "read -t 60 ...". An alternative implementation could be something like:

multiop $FILE Os &
pid=$!
...
wait $pid
