With guile at v2.0.0-134-g38c50a9, I'm getting a couple of failures in threads.test on my single core Debian Squeeze machine:
FAIL: threads.test: lock-mutex: timed locking succeeds if mutex unlocked within timeout FAIL: threads.test: mutex-ownership: mutex with owner not retained (bug #27450) Running just the threads.test *sometimes* works. One in six runs or so. -Dale
