Can one detect, via the AWS RDS API, any I/O suspension when creating a snapshot for a single-AZ DB instance?

Question

This is very similar to this existing question:

• amazon web services - RDS snapshot: how long does I/O suspension occur? - Server Fault

Unfortunately, the only answer provides more of a background about why a suspension is required/inevitable and neither answers that question more specifically nor provides any details sufficient to answer this question.

What I'd like to do is:

1. Disable all of the applications using a specific RDS instance.
2. Initiate creating a snapshot for the RDS instance.
3. Detect when any I/O suspension has ended.
4. Re-enable all of the applications using the RDS instance.

Is there a way to do [3] via the AWS RDS API? Could I, for instance, check the RDS instance status (and test that it's 'available')?
