No, the startup thread can be used as a regular HTTP thread, nothing in the code should prevent that. The globals code in the startup sequence is very tricky, but it should work. Either way - starting threads from an ISAPI filter/extension is completely forbidden (or at least strongly discouraged) so even if there is some bug in there, starting our own thread is not an option.
