The idea was to keep 100% API compatibility with Pathwatcher using Pulsar's public API (using require('atom').watchPath
code). The experiment lives on Pulsar
Pathwatcher repository
Because of the cyclic dependency between TextBuffer and Pulsar, together with the "exports" library and other issues, this experiment didn't go far. Some infinite loops happened, sometimes the renderer process crashed, and sometimes other weird issues appeared depending on the order things got loaded, so this will probably be revisited in the future, if at all.
