The first recording studio I helped assemble was a reasonably funded student
radio studios, it was fully analogue, 8-track, good mics .. at the time digital
was beginning to be available, but way beyond our means. It was possible to buy
a digital delay of maybe 10 seconds - I think they were mostly used as a buffer
on the main feed of talkback radio, or as part of very expensive effects units -
but it would have cost as much as the rest of the studio put together, which had
some reasonable gear, and substantially more than a modest sized home in the
cheapish inner suburb we were in.

This is a bogus argument.
Keeping software buffers does not help to reduce the number of
times the CPU has to wake up - this depends *only* on how much
the audio *hardware* is able to buffer. For this reason chips
designed for portable use have something like 2 seconds of
internal buffering.
320 MB corresponds to more than ** 13 minutes ** of stereo signal
in floating point format at 48 kHz. If an audio subsystem is using 320MB of memory
it's broken. Just dump it.
I think you followed Lennart's presentation @LAC2010 [1] explaining the
motivation for this: Pulseaudio keeps buffers sometimes 10 secs long or
even more. The reason for that is to have the CPU wake up as little as
possible in order to save power.
