The effects of the bug were twofold:
* A client actually requesting Reset_watches has the request rejected
* A client actually requesting Restrict got Reset_watches instead

a Reset_watches request got a hard error and the guest choked.

The ABI checking side, yes, but the -Og is a prerequisite which is
fairly self contained.
