Terrible implementation

Negative Comment by SagePtr
about Koala Aug 2016

Its 'watch' feature is implemented terrible (at least, on Windows). Instead of subscribing to directory change event, it's pulling files in infinite loop, causing locking issues under Windows. Under some conditions it can start fork bomb, when you put multiple files to watch in same directory - each file's watcher will race condition each other and spawn large amount on node.exe instaces (when you use external compiler. with internal - it will spawn multiple alert messages and won't work either).
So, I cannot recommend it. At least, under Windows. You can easily make your system hang due to fork bomb.
