FYI coreutils CI started failing with this on cfarm13.cfarm.net (debian 11.9) 
with:

FAIL: test-pthread-rwlock-waitqueue
===================================
test-pthread-rwlock-waitqueue.c:234: assertion 'startswith (do_test ("RRRRR"), " R1 
R2 R3 R4 R5")' failed
FAIL test-pthread-rwlock-waitqueue (exit status: 134)
