*) Fixed a potential bug in the 1.3.18 candidate that had the possibility of corrupting a module's string space if they replaced the r->hostname argument provided by the Apache core prior to http_vhost unescaping the hostname string. [Greg Stein, William Rowe]
*) Fixed system shutdown on Windows 2000 to assure that the modules have an opportunity to clean up. Note there is a _very_ limited amount of time in which to execute all cleanups [see MSKB Q146092] so all of the modules may still not be given an opportunity to complete their cleanups if they require more than 20 seconds total. [William Rowe]
*) Tidied up os/win32/service.c adding several info level debugging messages that helped resolve the second bullet point, and eliminated the service_cd() function since we 'do the right thing' in main() and now get our serverroot from the module's path instead of the current directory on Win32.
