Is parseGSI looking for a server on the network? In my limited
experience in this area, trying to connect to a database that is down
ties up the system (on a Mac at least) for some time -- I thought it
was more like two minutes -- whether called from the main thread or a
new thread.

Just to be clear, I am referring to attempting to connect to a server
with one of the database plugins. It isn't clear that that's what
you're doing, but your use of the term server suggests that might be
what's going on in your parseGSI function.
