:Release Notes:
Fix to reset spawned processes have default OOM settings rather than the
"priviledged" settings that ls-hubd has.

:Detailed Notes:
A recent change that gave ls-hubd processes "immunity" from the OOM
killer resulted in all dynamic services (which are spawned by ls-hubd)
receiving the same "immunity", which is bad.  This fix simply writes
"0" to /proc/PID/oom_adj for each dynamic service started; the kernel
then fills in the other settings.
