[omniORB] string_to_object deadlocks in v4.1.0

[Michael Kilburn]

Hi

I have stumbled upon a deadlock that happens if something goes wrong
during startup of my server. Sequence of actions look like:
- init orb
- activate RootPOA
- create Servant
- load IOR from file and call string_to_object(), if passed string is
bad (has extra space in my case) -- it deadlocks. I assume it tries to
throw.

100% reproducible.
