Ok, let's go for that one and hope it's the only one.
John, can I get a proper commit message and sign-off for that ashmem change?
Kirill - you mentioned that somebody reproduced a problem on x86-64
too. I didn't see that report. Was that some odd x86 Android setup
with Ashmem too, or is there something else pending?
