Yes, it's possible that temp file is not created because lazy stream
used to open temp file:
[[[
r1470936 | philip
Significantly reduce the number of open files during a typical update
over ra_serf by using lazy-opening streams to delay opening until the
HTTP response is received. This changes the new-in-1.8 lazy-open API.
]]]
Thus Subversion will crash if we got error before first write to
target stream. I've added check for this case in r1513156 and going
nominate it for backport to 1.8.x. Thanks for bug report!
