The OCI8 library can exec to Oracle in polling mode, i.e. the OCI call 
does not block in the oracle layer. The ruby interface uses polling to 
allow other ruby green threads to run. The only restriction is one 
polled exec per connection to the database. For multiple query threads, 
you must open a connection session for each query.
