I'm afraid I have to agree with Laszlo, that this patch unfortunately
does not cure the aarch64 race.
The test case I'm using is:
http://git.annexia.org/?p=rhbz1184405.git;a=tree
Note: This does not mean this patch is bad! Just that it doesn't cure
the long-standing aarch64 race that we've been trying to fix forever,
which is what we were hoping.
