It can be useful to be able to write a single-threaded test but run it as part of a multi-threaded program simply to exercise glibc synchronization code paths, e.g. the malloc implementation. This commit adds support to enable this kind of testing. Tests that define TEST_IN_THREAD, either as TEST_THREAD_MAIN or TEST_THREAD_WORKER, and then use support infrastructure (by including test-driver.c) will be accordingly run in either the main thread, or in a second "worker" thread while the other thread waits. This can be used in new tests, or to easily make and run copies of existing tests without modifying the tests themselves. Reviewed-by: Florian Weimer <fweimer@redhat.com>
