pooldaemon: increase min polling interval
Although we support '0' interval - it's highly inefficent to
do so many scans in busy-loop.
So ATM raise minimal rescan time to 100ms.
TODO: revisit whole timing logic here as it does have some sideeffect
hiddent impact and can considerably eat CPU in some cases.
