I'd appreciate a review of the pmcd rc script, especially the container behaviour at the 
end of the "start" case ...

Hi Ken, the rc_pmcd changes look ok on the surface, though we need to be 
careful when starting pmcd
in a container - the script blocks in pmpause (as "PID1" in the container 
instead of init). If a signal
is received (e.g. SIGCHLD when a background rc task completes), then the 
container will exit.

So I'm building new containers to test this thoroughly (the build takes ages 
....). Obviously
we need some container QA here - that's on my TODO list pending discussions 
with Nathan,
but holidays got in the way :)

I'll report back ..
