+* **Secondary process launch is not reliable.**
+
+ Recent memory hotplug patches have made multiprocess startup less reliable
+ than it was in the past. A number of workarounds are known to work depending
+ on the circumstances. As such it isn't recommended to use the secondary
+ process mechanism for critical systems. The underlying issues will be
+ addressed in upcoming releases.
