- Starting from some point after FreeBSD 5.2.1, valgrind did not terminate
correctly, but got stuck in state ``umtx''. This was mentioned on the lists
and in kern/68992 [closed], but I was never able to fix the problem.
On FreeBSD >= 502120, the kernel's and valgrind's definition of
UMTX_CONTESTED flag were out of sync, which is why valgrind did not terminate
on these systems.
