So would I, but I couldn't find another way in this case.

I patched 4 methods - clear, search, catalogObject, uncatalogObject.

Method clear is the simplest one - I simply flush the cache.

Methods catalogObject and uncatalogObject both invalidate the cache.
Should the transaction fail later the only drawback is that you threw
a few things out of the cache. They'll soon be re-entered by
subsequent searches.

Method search just inspects queries and stores results to memcache.

Can you give me an example where the cache would deliver non-committed data?
