Given how much callback based stuff exists in the Javascript world -- GUIs, Node.js and some recent W3C specs like the FileSystem API -- I thought it ought to be possible to write a simple sequencing function that can take care of this in the JS world. The key to a useful sequencing function is that it should let you customize the sequencing of the actions and recovery techniques pretty easily.

Here is my attempt at it - https://gist.github.com/2192413
