t0301: inconsistent test results

When running t0301 on NonStop platforms, we are seeing the subtests 21, 24, 25, and 27 failing occasionally but inconsistently under bash and /bin/sh. When run with the --verbose option and/or --debug options, the tests consistently succeed. This is perplexing and possibly a problem with our bash and/or /bin/sh, but isolating this is rough. Any advice?

Thanks,
Randall
