Hi Mark,

I took a look into ttl < 10s objects and saw that they are requests we
intentionally apply either "max-age=0, private" or "no-cache, private"
to. However their storage field is still "malloc Transient", and
transient storage usage only appears to be going up. 

Any ideas how to investigate further? 

It's varnish 5.0.0-1, and this didn't happen with 4.1, thought there
may well have been configuration changes since then.
