[omniORB] difference between orb->destroy and orb->shutdown

[Ferdinand Zaubzer]

What is the difference between orb->destroy and orb->shutdown?
I tried to use orb->destroy to be called when a term signal is recieved, but
it didn't work. With orb->shutdown it works fine. - Why?

Of course I didn't use orb->destroy or orb->shutdown in the signalhandler,
but I unlocked a mutex in a signalhandler that lets start a thread in which
orb->destroy or orb->shutdown was called.
