This is an updated version of VMStatsTraceControl-dtl for controlling
your VM stats logging. It is updated to take advantage of OSP 4.0.1 and
OSPP 4.0.1, which provide primitives to identify the (platform-dependent)
SIGUSR1 and SIGUSR2 signal numbers. It is backward compatible, using the
default values 10 and 12 respectively if the primitives are not available.

It also provides convenience methods VMStatsTraceControl class>>incrSigNum:
and VMStatsTraceControl class>>clearSigNum: to control the signals
to be monitored.

VMStatsTraceControl-dtl.9.cs.gz is the updated change set. I am also
attaching the original (unchanged) VMStatsInterpreterChanges-dtl.cs.gz
for completeness.
