OK. Build runs fine.

First trace under gdb, 2nd two freestanding.

In both cases I have loaded a bunch of code and am runnning large number
of tests in the unit test runner.

FYI,

PS: Many thanks for include order fix!!

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.
