This is a program that collects data from several different services. I was
hoping to make it more efficient by enabling different threads to do the
collection in parallell. The service answers promptly when called from the
main thread, but when called from it's own thread it just stops on the close
method of the StreamWriter. I've incorporated a timeout to abort any
collection thread that uses more than a specified amount of time, and this is
what finally throws a ThreadAbort exception. While the close call is
"waiting" the cpu usage for the aspnet process is hovering around 90% cpu
usage. Extending the timeout period doesn't change anything. I'm actually
seeing the same problem with another collection function that interfaces with
a web service..
