Segfault during image saving & GC #762
Description

pthread_setschedparam failed: Operation not permitted
This VM uses a separate heartbeat thread to update its internal clock
and handle events. For best operation, this thread should run at a
higher priority, however the VM was unable to change the priority. The
effect is that heavily loaded systems may experience some latency
issues. If this occurs, please create the appropriate configuration
file in /etc/security/limits.d/ as shown below:
cat <<END | sudo tee /etc/security/limits.d/squeak.conf
* hard rtprio 2
* soft rtprio 2
END
and report to the squeak mailing list whether this improves behaviour.
You will need to log out and log back in for the limits to take effect.

Is this my fault or a bug in the VM? I only saw this once so far.
