It turns out that this was an SELinux issue. Mono normally runs in its 
own domain, mono_t, which can do execmem and execheap. Under mock, the 
domain transition to mono_t doesn't happen and so it runs in 
unconfined_t and breaks with an execheap violation. I've fixed this by 
writing a policy module for mock and running mock in its own domain, 
mock_t, rather than turning on the allow_execheap and allow_execmem

Good spot, thanks.
