Hi Ondrej,

Why use 2 seconds for the polling interval?

I'm sure you have a good reason for this and it should be in the
commit message or as a comment in the code.

I otherwise have no objection to this change.

thanks,

Agreed, please post this with a better commit message, specifically
make sure you explain why the interval is being changed and why
2*HZ is specifically being choosen.

Thanks.
