There are known issues in job handling under dash and some ksh variants, where a parallel testsuite can hang or cause a 100% processor load. In the current release, the overall autoconf testsuite only exercises parallel autotest under bash and zsh, or if you have defined TEST_PARALLEL_AUTOTEST in the environment. Meanwhile, Cygwin has known problems with named fifos that cause failures when attempting parallel tests in an autotest suite. It is possible that other difficulties will be encountered, whether with shell or platform limitations; help is appreciated in improving parallel testsuite support.
