As a suggestion, it could be a wininet bug.  Should wininet be caching the file
and returning the cached version instead of downloading it every time?  As a
further suggestion, it could be a crypt32 bug.  Should crypt32 be caching the
chain it builds to verify the signature, rather than recreating the chain every
time?

If there's a way to use a native wininet to test, you might be able to rule out
whether it's a wininet bug.  I don't think it's really possible to run native
crypt32 (at least, I've never gotten it to work for me.)
