increase rt.limit from 200ms to 2seconds

200ms seems a little small, some plugins initialize themselves from the
RT thread and get killed. 2 seconds seem to be a better default.

The important part is that there is a limit so that runaway processes
are killed and don't lock up the system.

Fixes #1344
