Description:
mysqlimport executed with --use-threads returns random exit code. This is most likely a threading issue where one of the child threads affects the exitcode when they exit after the main thread.

How to repeat:
./mysql-test-run.pl --do-test=mysqldump

Suggested fix:
Wait for the child threads to exit before exiting from the main loop.

Found that mysqlimport has crashed. Thus 'pclose' in mysqltest returns -1 and errno 10(ECHILD).
