Hi Sean,

This looks good.

> d.macdonald at auckland.ac.nz originally reported this issue and I'll be marking the fix as contributed by him. He's already signed the OCA. There's a good description in bug report. We have a race like condition if the corba server is shut down while there are still workers/client threads in a waiting queue waiting for server. The issue arises when the purgeCalls method marks a socket state as ABORTed or CLOSE_RECVD but fails to remove that socket from the socket connectionCache. Fix is to wrap the removal of the socket in a finally block.
