Turns out the trouble in comment 5 was due to my forgetting to remove the
nptl/pthread_cond*.S files before building the library this time around. The
original 0001 patch did indeed function correctly. I have reworked the patches,
improved the patch headers and naming as well as added a new tst-condpi2.c
testcase which tests for priority inversion avoidance. A follow-on patch detects
an unbounded inversion and exits gracefully. Without the last patch, the glibc
test framework will kill the test after the 2 second timeout - which may be the
preferred approach. I'll attach the updated patches now.
