I tried a test w/ four processes simultaneously issuing memcache gets as fast as they can.. each took 20-30 sec to do 1000 gets. No failures. Guarding against whitespace in malformed IDs now.
Is it normal for memcache to fail sometimes? Like 0.1% of the time? (if it just goes through the misses the cache silently on a read, not so bad, but if it fails to delete from the cache on a save/delete, then that is bad)
