Thanks. Thats nice to read.

I will just be setting this to 200000 for now and see how that goes.

I hope that at some time a better kernel notification mechanism becomes 
available. I wonder whether kernel developers are aware of the issues 
desktop file indexing has with the current mechanisms. I can file some 
detailed bug report or enhancement request with kernel.org and try to get 
in touch with some kernel developers about it, if that would be of help.

Thanks,
