Agreed. I have replaced the Assert with this in the attached v4 patch.

	Assert(initsize >= 1 && initsize <= MaxAllocSize);

Note, I changed "initsize > 0" to "initsize >= 1" to better match with
the comment:

>  * The valid range for 'initsize' is 1 to MaxAllocSize.

If there's no objection, I am going to commit the patch.
