/**
 * Base contract that all upgradeable contracts should use.
 * 
 * Contracts implementing this interface are all called using delegatecall from
 * a dispatcher. As a result, the _sizes and _dest variables are shared with the
 * dispatcher contract, which allows the called contract to update these at will.
 * 
 * _sizes is a map of function signatures to return value sizes. Due to EVM
 * limitations, these need to be populated by the target contract, so the
 * dispatcher knows how many bytes of data to return from called functions.

At Fotopedia, we use Unicorn to serve our main Rails application. Every day, we restart our application several times, spawning and killing hundred of Unicorns. Managing graceful restarts is a complex task, and requires careful monitoring and command. This article introduces our tool Polycorn, a Unicorn management program.
