Graceful process restarts in Go (library)

It is sometimes useful to update the running code and / or configuration of a network service, without disrupting existing connections. Usually, this is achieved by starting a new process, somehow transferring clients to it and then exiting the old process.

There are many ways to implement graceful upgrades. They vary wildly in the trade-offs they make, and how much control they afford the user. This library has the following goals:

 - No old code keeps running after a successful upgrade
 - The new process has a grace period for performing initialisation
 - Crashing during initialisation is OK
 - Only a single upgrade is ever run in parallel
