Watching for entity changes on Windows in a Syncthing folder produces exceptions due to filesystem locks

[carltonwhitehead]

On Windows, Syncthing appears to place a lock on files when updates are replicating from other hosts in the cluster. Snoozle's file watcher receives modification events before Syncthing has released its lock, leading to errors when attempting to read the file. This is a critical issue for running Snoozle based apps on Windows.

Possible solutions:

• Investigate Syncthing configuration options on Windows related to file locking behavior
• Use a task queue in front of I/O operations

The 0.3 branch significantly improves the robustness of the watch stream. Will re-test once it gets closer to merge time.
