* when cond var is destroyed, in the PRE, report an error if nwaiters > 0. * when cond_wait succeeds, get the cond var but do not create one in helgrind (it must exist if cond_wait was done). Report an error if cond not found (assuming this is caused by a destroy done while the thread was cond_wait-ing). * added a test git-svn-id: svn://svn.valgrind.org/valgrind/trunk@12721
