[iolib-devel] Running io handler periodically

Hello! Is it possible to make io handler, that will be running periodically, i.e. not every time when io will be possible? `iomux:set-io-handler' have `:timeout' &key parameter, but, as i understand, it is poll timeout. Of course I cat call `sleep' inside io handler body, but it will be freeze all other handlers in this thread too. So, can I run `iomux:event-base' io handler periodically w/o `sleep' dirty hack? Thank you. Nikolay.
