actually, this is the opposite of the intent.

softmode is there mostly for people who want to use JACK in, for
example, live situations where the occasional xrun is not a disaster.
they want realtime latency settings, but don't want any clients kicked
out if there is an xrun. if the watchdog doesn't work in softmode, its a
bug.
