On my system (Windows XP, VC++ 6, Apache/2.2.2), there's
essentially no difference in speed between the four
programs in cleaning things up, and like you, all temp
files are gone at the end. I'm afraid I'm stuck ...
Since for you apr_temp/apr_temp_sh (fast) and
apr_temp_nc/apr_temp_nc_sh (hangs a minute) pairwise
behave similarly, that suggests APR_SHARELOCK isn't
relevant (which is supported by it's apparent lack of
relevance to this problem in the Apache sources). 
APR_FILE_NOCLEANUP does seem to make a (negative)
difference in speed, but perhaps
is relevant here. In any case, the above results suggests
undefined would be better, which makes sense, but
both apparently help in the Perl glue on Win32. Sigh ...

I'm wondering the following ... The failed upload
tests (15, 16, and/or 20), for me, involve uploading
the perl.exe binary. Is that the same for you? Might
there be a problem with uploading a file which is
a program that might be in use at the time? Does the
attached patches against
which removes the
line, and
which skips using perl.exe (and httpd.exe) for
the upload tests on Win32 work for you?
