I've long been baffled by code in httpd to carefully initialize global
variables to 0.  (I vaguely recall a comment about Netware having an issue
there.)

What are the situations where this isn't 0 on load of httpd, and what does
this have to do with "clean stack" as suggested in the commit message?
