Thanks for your comments, being new here I cut and pasted an earlier

I did test on testbot, at the time I did not realise they VMs there are
actual systems I thought they were running the Wine dlls, you educated me
to this earlier in the week, makes more sense now. The 65536 comes from
Wine's kernel32/path.c,  https://source.winehq.org/git/wine.
git/blob/HEAD:/dlls/kernel32/path.c#l1159 so I used it to test locally,
they tests failed on testbot as it uses native win32. The test needs to be
removed/rethought as none of the VMs actually call the progress function
when copying a 128Mb file.

Thanks again for your comments.
