At this moment, none. The best I can do is add a class variable to allow you to
set its class-type value to a TFPHTTPConnectionThread class descendant,
then that descendant would be used. Then you set this variable at the start.

Another option is to create a ConnectionThreadStackSize variable that would
be used to set the stack size.
