New issue 384 by [email protected]: Avoid remounting system partition on Android
https://code.google.com/p/address-sanitizer/issues/detail?id=384

Remount suppresses future OTAs and is generally dangerous.

The following approach would require changing Android code but is much safer.

The idea is to add a persistent system property that specifies a zygote wrapper at OS startup (much like wrap.* properties used for Valgrind, but those are used when fork()-ing the Zygote, and the new one will be used when starting the Zygote, just once).

Then we could move the zygote wrapper and the runtime library to /data (or some other writable place). We would still need a rooted device, of course.
