Do you need to mitigate potential EMFILE/ENFILE problems? You're potentially
trebling up the number of accounted systemwide fds: one for erofs itself, one
anonfd per cache object file to communicate with the daemon and one in the
daemon to talk to the server. Cachefiles has a fourth internally, but it's
kept off the books - further, cachefiles closes them fairly quickly after a
period of nonuse.
