Change default to be 'process all events before calling daemon.'

Also, put a small work around into devd to prevent a hang on boot this
would cause because select used to return 2 rather than 0 for no
evetnts due to a bug I fixed a few days ago in subr_bus.c.  I'll
remove this workaround May 7th.  You have until then to upgrade your
kernel if you want to run a new devd with an older kernel.
