media_unittests under drmem hangs right after reporting the invalid heap arg it's not DRi#875 -no_check_delete_mismatch => still hangs natively => hangs! so I was going to file a chromium issue, except this test works natively (and under DR) for Qin so perhaps there is some drmem issue here too.
I will exclude it from the bots for now.
no DR or DrMem on any callstack. no cpu usage.
