make check sometimes hangs

[Stefan Westerfeld <stefan space twc de>]

   Hi!

If I run

  cd tests/audio; while :; do make check; done

in beast, I'd expect that the audio tests would be done over and over again,
forever. However, what happens here is that after some time, make check hangs,
nothing happens any more. Looking at pstree there is

-bash---python---sh---python---sh---bse2wav.sh---lt-bsetool---2*[{lt-bsetool}]

so bsetool for some reason hangs. Without CPU usage. Maybe some kind of
deadlock, possibly triggered by the use of the null driver?

That wasn't always the case. I saw the problem when using a variant of
bse2wav.sh for SpectMorph testing - compared to make check in beast, I need to
render a lot more wave files here. And that used to work when I made the last
SpectMorph release, about six weeks ago.

   Cu... Stefan
