The probability that two 64k vmallocs will fail is pretty low,
and the probability that after that failure there is enough memory
for an audio application to be executed successfully is even lower.

Nevertheless, in that unlikely case I would prefer max 0.37 seconds
of silence (=skipped audio) during resume to a failed start of a
recording caused by an unloaded module. Limited functionality
is better than complete failure.
