Comment 3 for bug 867918

Using ZSYSTEM to fire off a number of MUPIP INTRPT has a fair amount of overhead. You can instead use the lightweight $ZSIGPROC(pid,signal) function to send a signal - it returns 0 for success 1 for failure. The downside of the API is that you have to specify the signal numerically, which makes the code less portable. Also, the documented & recommended MUPIP INTRPT API will remain upward compatible in the (unlikely) event we decide to change the mechanism.

Yes, $zsigproc() should be documented. It will be one day.
