--- Comment #7 from bob at bob131.so ---
In the specific case of blender, there are 31 hung up threads with around 9
each waiting on

__lll_lock_wait () at ../sysdeps/unix/sysv/linux/x86_64/lowlevellock.S:135
pthread_cond_wait@@GLIBC_2.3.2 () at
../sysdeps/unix/sysv/linux/x86_64/pthread_cond_wait.S:185
do_futex_wait () at ../sysdeps/unix/sysv/linux/futex-internal.h:205

The remaining threads are waiting on poll () at
../sysdeps/unix/syscall-template.S:84 with the last being the one I provided a
backtrace for. Is there any one you're interested in particular? After sampling
some of the backtraces they seem to be unrelated, either blender-specific or
just mainloops for udev and pulseaudio waiting for events, but if please let me
know if there's any backtraces you'd like
