stream: preserve volatile cache early Since cache file are not protected by the lock, their state might change between their initial detection, the computation of their size and they preservation by the VolatileManager. So we gather all theses step in a single one to avoid such race. This also handle disappearing cache file in the "copy/hardlink" clone cases.
