> In order to minimize locking and interference with channels, AMI should attempt to use the stasis cache where possible when looking up data on a channel. This includes the following:
> h4. manager.c
> * GetVar - channel snapshots should contain their channel variables. We can simply look at the snapshot's manager_vars field and return the value from it.
> * CoreShowChannels - this should only hit the Stasis channel cache.
> h4. cli.c
> * core show channels - inspect the channels using the stasis cache
> * core show channel. It may be worthwhile to not print out the information that can't be obtained from the cache, simply to minimize the impact of this command.
