Win32 doesn't have mktemp, so thats not *strictly* true.
I think that refers to the cleanup set by apr_file_mktemp,
which in turn comes from apr_file_open (on Win32).
FYI,
http://svn.apache.org/viewvc/apr/apr/trunk/file_io/unix/mktemp.c?r1=62405&r2=62404&pathrev=62405
The cleanup on Win32 was removed from apr here... I'll bet that's it!
The explicit cleanup was removed there, but replaced by
APR_DELONCLOSE (set by default), which if set would
delete the file on close. But, as the comment explains,
can't be used here ...
But I think you're on the right track, in that the
problem with the temp files sticking around (and
apparently causing the occasional errors when the
upload.t test is run multiple times) comes from the
cleanup set by apr_file_open. I tried this patch:

which seems to help - when the upload.t test is run
multiple times, I get far fewer temp files left over
(although the occasional ones do stick around), and
even when they are there, I haven't seen any failures
yet. Steve, does this help you?
