Summary:     4.0-dev and compatibility release: NVDA will no longer appear to 
freeze when attempting to connect to a streaming server.
Threads allows a program to run several things concurrently. Using this 
facility, one can run a function in the background when called from a script.
Using threads resolve an issue where NvDA appears to freeze when trying to 
connect to a streaming server.
As this is important for SPL 4.x users, this will be available in both 4.0-dev 
and the compatibility release.
