+Here's some notes I got from Dave Jones at Red Hat:
+You're probably better off asking Ingo <mingo@redhat.com>
+Here's what I've managed to get out of him so far..
+they should either allocate those dynamic buffers via mmap(PROT_EXEC)
+(best method), or should do a mprotect(PROT_EXEC) over the affected
+pages (acceptable method), or should define the app to have an
+executable stack (worst method).
+how do these apps work on amd64/ia64?
+(I guess Ingo means given they too have non executable stacks)
