workaround

(In reply to Leandro Lupori from comment #3)
This is not a powerpc-specific problem, it's a limitation of memguard: some of
its internal operation involve allocating from UMA, which might call into
memguard again.  The attached patch should allow you to guard most UMA buckets.
 It's a total hack and isn't intended to be committed, but might help you make
progress with the use-after-free.
