That's not correct. Valgrind's helgrind had support for QMutex specifically.
Helgrind needed to know when a mutex was locked or unlocked, in order to
present its warnings. To do that, it specifically overrides the QMutex::lock
and unlock functions.
I don't know about DRD.
As for Qt 5, since locking and unlocking is inlined into the user code,
valgrind might be completely unable to work.
