This must be a valgrind issue, there would be major problems if the OS isn't able to lock

is getting confused by a recursive mutex? LLDB uses recursive mutexes.W
LLDB's Predicate.h uses plain std::mutex, which is not recursive, and
std::lock_guard/std::unique_lock
on top of it.
This needs more digging in because the latest Valgrind snapshot reports the same
"impossible" condition.
