Hold on! It does not, but it do fail with an error. It just sit there,
not exiting despite -d 3 and spin. If I strace the running process, I get:

    etienne@curst:~$ strace -p 7019
    Process 7019 attached - interrupt to quit
    restart_syscall(<... resuming interrupted call ...>

If I kill arecord with Ctrl-C, the test.wav is empty.

Attaching the output of strace -f -o /tmp/arecord-memmap.strace -s 1024
-v arecord -M -D hw:1,0 -d 3 -f cd -t wav test.wav
