yes, it requested more exclusive access than the handle from
QTemporaryFile, by not allowing shared writing on the file.
which is not what fopen() does as we've discussed on their ML.

libzip:
CreateFile[A / W](ctx->fname, GENERIC_READ, FILE_SHARE_READ, NULL,
OPEN_EXISTING, FILE_ATTRIBUTE_NORMAL, NULL);

the patch to fix that is pending to be pushed and contains:
FILE_SHARE_READ | FILE_SHARE_WRITE
