I've ran into this failure today:

... and indeed, there were lots of stale qmp-in-* and qmp-out-*
files in my scratch directory, ultimately causing the above failure
after a couple of days.
After some more testing, it seems like test 192 is not cleaning up
correctly:
$ ls scratch/
$ ./check -qcow2 192
[...]
192 0s ...
Passed all 1 tests
$ ls scratch/
nbd qemu-0.pid qmp-in-8772_0 qmp-out-8772_0
Any ideas how to fix this in a clean way (e.g. simply add a
"rm -f scratch/..." at the end of the script) ?
