The current implementation of posix/osiSpawnDetachedProcess()
basically just forks and execs. The new process inherits the
scheduling policy and priority of whoever called spawnDetachedProcess().
This means e.g., that a caRepeater spawned by a "real-time enabled"
IOC application executes under SCHED_FIFO with priority 51.
Not sure this is a good thing. IMO osiSpawnDetachedProcess()
should be fixed so that the new process starts out with SCHED_OTHER.
