+ * pmResult rewriting is complicated because ...
+ *
+ * - deleting a metric involves moving all of the following rp->vset[]
+ * entries "up" one position and decrementing rp->numpmid
+ * - deleting an instance involves moving all of the following
+ * rp->vset[i]->vlist[] enties "up" one position and then decrementing
+ * rp->vset[i]->numval
+ * - rescaling values involves calling __pmStuffValue which modifies
+ * rp->vset[i]->vlist[j].value, and in the case of all types other than
+ * U32 or 32 this will involve an allocation for a new pmValueBlock
+ * ... we need to keep track of the previous pmValueBlock (if any) to
+ * avoid memory leaks
+ * - changing type has the same implications as rescaling
+ * - a single metric within a pmResult may have both rescaling and type
+ * change
+ * - the initial pmResult contains pointers into a PDU buffer so the fast
+ * track case in pmFreeresult() may not release any of the pmValueSet
+ * or pmValue or pmValueBlock allocations if pmFreeResult is given a
+ * rewritten pmResult, so we modify the pmResult in place but use save[]
+ * to remember the original pmValueSet when retyping or rescaling, use
+ * orig_numval[] to remember how many pmValue instances we had had for
+ * each pmValueSet, and use orig_numpmid to remember the original numpmid
+ * value
